IDENTITY
========
_____
<1.1> What is `identity' on the internet?
Generally, today people's `identity' on the internet is primarily
determined by their email address in the sense that this is their
most unchanging 'face' in the electronic realm. This is your
login name qualified by the complete address domain information,
for example ``ld231782@longs.lance.colostate.edu''. People see
this address when receiving mail or reading USENET posts from you
and in other situations where programs record usage. Some obsolete
forms of addresses (such as BITNET) still persist.
In email messages, additional information on the path that a message
takes is prepended to the message received by the recipient. This
information identifies the chain of hosts involved in the
transmission and is a very accurate trace of its origination. This
type of identify-and-forward protocol is also used in the USENET
protocol to a lesser extent. Forging these fields requires
corrupted mailing software at sites involved in the forwarding and
is very uncommon. Not so uncommon is forging the chain at the
origination point, so that all initial sites in the list are faked
at the time the message is created. Tracing these messages can be
difficult or impossible when the initial faked fields are names of
real machines and represent real transfer routes.
_____
<1.2> Why is identity (un)important on the internet?
The concept of identity is closely intertwined with communication,
privacy, and security, which in turn are all critical aspects of
computer networks. For example, the convenience of communication
afforded by email would be impossible without conventions for
identification. But there are many potential abuses of identity
possible that can have very severe consequences, with massive
computer networks at the forefront of the issue, which can
potentially either exacerbate or solve these problems.
Verifying that an identity is correct is called `authentication',
and one classic example of the problems associated with it is
H.G. Well's ``War of the Worlds'' science fiction story adapted to a
radio broadcast that fooled
segments of the population into thinking that an alien invasion was
in progress. Hoaxes of this order are not uncommon on Usenet and
forged identities makes them more insidious. People and their
reputations can be assaulted by forgery.
However, the fluidity of identity on the internet is for some one of
its most attractive features. Identity is just as useful as it is
harmful. A professor might carefully explain a topic until he
finds he is talking to an undergraduate. A person of a particular
occupation may be able to converse with others who might normally
shun him. Some prejudices are erased, but, on the other hand, many
prejudices are useful! A scientist might argue he can better
evaluate the findings of a paper as a reviewer if he knows more
about the authors. Likewise, he may be more likely to reject it
based on unfair or irrelevant criteria. On the other side of the
connection, the author may find identities of reviewers useful in
exerting pressure for acceptance.
Identity is especially crucial in establishing and regulating
`credit' (not necessarily financial) and `ownership' and `usage'.
Many functions in society demand reliable and accurate techniques
for identification. Heavy reliance will be placed on digital
authentication as global economies become increasingly electronic.
Many government functions and services are based on identification,
and law enforcement frequently hinges on it. Hence, employees of
many government organizations push toward stronger identification
structures. But when does identification invade privacy?
The growth of the internet is provoking social forces of massive
proportions. Decisions made now on issues of identity will affect
many future users, especially as the network becomes increasingly
global, universal, widespread, and entrenched; and the positive or
adverse affects of these actions, intended and inadvertent, will
literally be magnified exponentially.
_____
<1.3> How does my email address (not) identify me and my background?
Your email address may contain information that influences people's
perceptions of your background. The address may `identify' you as
from a department at a particular university, an employee at a
company, or a government worker. It may contain your last name,
initials, or cryptic identification codes independent of both. In
the US some are based on parts of social security numbers. Others
are in the form 'u2338' where the number is incremented in the
order that new users are added to the system.
Standard internet addresses also can contain information on your
broad geographical location or nationhood. However, none of this
information is guaranteed to be correct or be there at all. The
fields in the domain qualification of the username are based on
rather arbitrary organization, such as (mostly invisible) network
cabling distributions. The only point to make is that early fields
in the address are more specific (such as specific computer names
or local networks) and the later ones the most general (such as
continental domains). Typically the first field is the name of the
computer receiving mail.
Gleaning information from the email address alone is sometimes an
inspired art or an inconsistent and futile exercise. (For more
information, see the FAQs on email addresses and known
geographical distributions below.) However, UNIX utilities exist
to aid in the quest (see the question on this).

_____
<1.4> How can I find out more about somebody with a given email address?
One simple way is to send email to that address, asking. Another
way is to send mail to the postmaster at that address (i.e.
postmaster@address), although the postmaster's job is more to help
find user ID's of particular people given their real name and solve
mail routing problems. The sysadmin (i.e. `root@address') may also
be able to supply information. Users with related email address
may have information. However, all of these methods rely on the
time and patience of others so use them minimally.
One of the most basic tools for determining identity over the
internet is the UNIX utility 'finger'. The basic syntax is:
finger user@here.there.everywhere
This utility uses communication protocols to query the computer
named in the address for information on the user named. The
response is generated completely by the receiving computer and may
be in any format. Possible responses are as follows:
- A message `unknown host' meaning some aspect of the address is
incorrect, two lines with no information and '???'.
- A message 'In real life: ???' in which case the receiving computer
could not find any kind of a match on the username. The finger
utility may return this response in other situations.
- A listing of information associated with multiple users. Some
computers will search only for matching user IDs, others will
attempt to find the username you specified as a substring of all
actual full names of users kept in a local database.
At some sites 'finger' can be used to get a list of all users on the
system with a `finger @address'. In general this is often
considered weak security, however, because `attackers' know valid
user ID's to `crack' passwords.
More information on the fields returned by `finger' is given below.
More information on `finger' and locating people's email addresses
is given in the email FAQ (such as the WHOIS lookup utility). Just
as you can use these means to find out about others, they can use
them to find out about you. You can `finger' yourself to find out
what is publicly reported by your UNIX system about you. Be
careful when modifying `finger' data; virtually anyone with
internet access worldwide can query this information. In one
famous case, the New York Times writer J. Markoff uncovered the
identity of R. Morris, author of the Internet Worm, through the
use of `finger' after an anonymous caller slipped by revealing his
initials which were also his login ID. See the book Cyberpunk by
K. Hafner and J. Markoff.
_____
<1.5> Why is identification (un)stable on the internet?
Generally, identity is an amorphous and almost nonexistent concept
on the Internet for a variety of reasons. One is the inherent
fluidity of `cyberspace' where people emerge and submerge
frequently, and absences are not readily noted in the `community'.
Most people remember faces and voices, the primary means of casual
identification in the 'real world'. The arbitary and cryptic
sequences of letters and digits comprising most email addresses are
not particularly noticeable or memorable and far from a unique
identification of an individual, who may use multiple accounts on
multiple machines anywhere in the world.
Currently internet users do not really have any great assurances
that the messages in email and USENET are from who they appear to
be. A person's mailing address is far from an identification of an
individual.
- Anyone with access to the account, e.g. they know the password,
either legitimately or otherwise, can send mail with that address
in the From: line.
- Email addresses for an individual tend to change frequently as
they switch jobs or make moves inside their organizations.
- As part of current mailing protocol standards, forging the From:
line in mail messages is a fairly trivial operation for many
hackers.
The status and path information prepended to messages by
intermediate hosts is generally unforgeable. In general, while
possible, forgeries are fairly rare on most newsgroups and in
email. Besides these pathological cases abve there are many basic
problems with today's internet protocols affecting identification
on the internet:
- Internet mail standards, described in RFC-822, are still evolving
rapidly and not entirely orderly. For example, standards for
mail address `munging' or `parsing' tend to vary slightly between
sites and frequently mean the difference between finding
addresses and bouncing mail.
- Domain names and computer names are frequently changed at sites,
and there are delays in the propagation of this data.
- Addresses cannot be resolved when certain critical computers
crash, such as the receiving computer or other computers involved
in resolving names into addresses called `nameservers'.
- A whole slew of problems is associated with `nameservers'; if
they are not updated they will not find name addresses, and even
the operation of what constitutes `updating' has different
interpretations at different sites.
The current internet mailing and addressing protocols are slightly
anachronistic in that they were created when the network was
somewhat obscure and not widespread, with only a fraction of the
traffic it now sees. Today a large proportion of internet traffic
is email, comprising millions of messages.
_____
<1.6> What is the future of identification on the internet?
Some new technologies and standards are introducing facial images
and voice messages into mail and these will improve the sense of
community that comes from the familiarity of identification.
However, they are not currently widespread, require large amounts
of data transfer, standardized software, and make some compromises
in privacy.
Promising new cryptographic techniques may make 'digital signatures'
and 'digital authentication' common (see below). Also, the trend
in USENET standards is toward greater authentication of posted
information. On the other hand, advances in ensuring anonymity
(such as remailers) are forthcoming. See below.
PRIVACY
=======
_____
<2.1> What is `privacy' on the internet?
Generally, while `privacy' has multiple connotations in society and
perhaps even more on the internet, in cyberspace most take it to
mean that you have exclusive use and access to your account and the
data stored on and and directed to it (such as email), and you do
not encounter arbitrary restrictions or searches. In other words,
others may obtain data associated with your account, but not
without your permission. These ideas are probably both fairly
limiting and liberal in their scope in what most internet users
consider their private domains. Some users don't expect or want
any privacy, some expect and demand it.
_____
<2.2> Why is privacy (un)important on the internet?
This is a somewhat debatable and inflammatory topic, arousing
passionate opinions. On the internet, some take privacy for
granted and are rudely surprised to find it tenuous or nonexistent.
Most governments have rules that protect privacy (such as the
illegal search and seizure clause of the U.S. constitution, adopted
by others) but have many that are antithetical to it (such as laws
prohibiting secret communications or allowing wiretapping). These
rules generally carry over to the internet with few specific rules
governing it. However, the legal repercussions of the global
internet are still largely unknown and untested (i.e. no strong
legal precedents and court cases). The fact that internet traffic
frequently passes past international boundaries, and is not
centrally managed, significantly complicates and strongly
discourages its regulation.
_____
<2.3> How (in)secure are internet networks?
- `Theoretically' people at any site in the chain of sites with
access to hardware and network media that transmits data over the
Internet could potentially monitor or archive it. However, the
sheer volume and general 'noise' inherent to this data makes
these scenarios highly improbable, even by government agencies
with supposedly vast funding and resources.
- Technologies exist to `tap' magnetic fields given off by
electrical wires without detection. Less obscurely, any machine
with a network connection is a potential station for traffic
detection, but this scenario requires knowledge and access to
very low-level hardware (the network card) to pursue, if even
possible.
- A company Network General Inc. is one of many that manufactures
and markets sophisticated network monitoring tools that can
'filter' and read packets by arbitrary criteria for
troubleshooting purposes, but the cost of this type of device is
prohibitive for casual use.
Known instances of the above types of security breaches at a major
scale (such as at network hubs) are very rare. The greatest risks
tend to emerge locally. Note that all these approaches are almost
completely defused with the use of cryptography.
_____
<2.4> How (in)secure is my account?
By default, not very. There are a multitude of factors that may
reinforce or compromise aspects of your privacy on the internet.
First, your account must be secure from other users. The universal
system is to use a password, but if it is `weak' (i.e. easy to
guess) this security is significantly diminished. Somewhat
surprisingly and frighteningly to some, certain users of the
system, particularly the administrator, generally have unlimited
access regardless of passwords, and may grant that access to
others. This means that they may read any file in your account
without detection.
Furthermore, not universally known, most UNIX systems keep fairly
extensive accounting records of when and where you logged in, what
commands you execute, and when they are executed (in fact, login
information is usually public). Most features of this `auditing' or
`process accounting' information are enabled by default after the
initial installation and the system administrator may customize it
to strengthen or weaken it to satisfy performance or privacy aims.
This information is frequently consulted for troubleshooting
purposes and may otherwise be ignored. This data tracks
unsuccessful login attempts and other 'suspicious' activities on
the system. A traditional part of the UNIX system that tracks user
commands is easily circumvented by the user with the use of
symbolic links (described in 'man ln').
UNIX implementations vary widely particularly in tracking features
and new sophisticated mechanisms are introduced by companies
regularly. Typically system adminstrators augment the basic UNIX
functionality with public-domain programs and locally-developed
tools for monitoring, and use them only to isolate `suspicious'
activity as it arises (e.g. remote accesses to the 'passwd' file,
incorrect login attempts, remote connection attempts, etc.).
Generally, you should expect little privacy on your account for
various reasons:
- Potentially, every keystroke you type could be intercepted by
someone else.
- System administrators make extensive backups that are completely
invisible to users which may record the states of an account over
many weeks.
- Erased files can, under many operating systems, be undeleted.
- Most automated services keep logs of use for troubleshooting or
otherwise; for example FTP sites usually log the commands and
record the domain originations of users, including anonymous
ones.
- Some software exacerbates these problems. See the section on
``X Windows (in)security''.
Indepedent of malevolent administrators are fellow users, a much
more commonly harmful threat. There are multiple ways to help
ensure that your account will not be accessed by others, and
compromises can often be traced to failures in these guidelines:
- Choose a secure password. Change it periodically.
- Make sure to logout always.
- Do not leave a machine unattended for long.
- Make sure no one watches you when you type your password.
- Avoid password references in email.
- Be conservative in the use of the .rhost file.
- Use utilities like `xlock' to protect a station, but be
considerate.
Be wary of situations where you think you should supply your
password. There are only several basic situations where UNIX
prompts you for a password: when you are logging in to a system or
changing your password. Situations can arise in which prompts for
passwords are forged by other users, especially in cases where you
are talking to them (such as Internet Relay Chat). Also, be aware
that forged login screens are one method to illegitimately obtain
passwords.

_____
<2.5> How (in)secure are my files and directories?
The most important privacy considerations are related to file
rights, and many lapses can be traced to their misunderstood nature
or haphazard maintenance. Be aware of the rights associated with
your files and directories in UNIX. If the `x' (`execute') right on
your parent directory is off for users, groups, and other, these
users cannot gain information on anything in your directories.
Anything less may allow others to read, change, or even delete
files in your home directory. The rights on a directory supersede
the rights associated with files in that directory. For a
directory, 'x' means that access to the files (or subdirectories)
in the directory is possible -- if you know their names. To list
the contents of the directory, however, requires the 'r' right.
By default most accounts are accessable only to the owner, but the
initial configuration varies between sites based on administrator
preference. The default file mode specifies the initial rights
associated with newly created files, and can be set in the shell
with `umask'. The details of rights implementations tend to vary
between versions of UNIX. Consult man pages on `chmod' and `ls'.
Examples
--------
traver.lance % ls -ld ~
drwx------ 15 ld231782 1536 Jan 31 21:22 /users/ld231782/
Here is a listing of the rights associated with a user's home
directory, denoted by `~'. The columns at the left identify what
rights are available. The first column identifies the entry as a
directory, and the next three columns mean that read, write, and
execute rights, respectively, are permitted for that user. For
directories, the `x' right means that contents (file and
subdirectory names) within that directory can be listed. The
subsequent columns indicate that no other users have any rights to
anything in the directory tree originating at that point. They
can't even `see' any lower files or subdirectories; the hierarchy
is completely invisible to them.
traver.lance % ls -l msg
-rw-r--r-- 1 ld231782 35661 Jan 29 23:13 msg
traver.lance % chmod u=rw,g=,o= msg
traver.lance % ls -l msg
-rw------- 1 ld231782 35661 Jan 29 23:13 msg
Here the modes on the file `msg' were changed to take away rights
from `group' and `other'.
Note that `ls -l <file>' requires both the 'r' right to get the list
of files and subdirectories, and the 'x' right to access the files
and subdirectories in order to get their size, etc. For example,
suppose the directory `foo' has rights dr--r--r--, the following
is possible:
ls foo
These commands would fail independent of file rights:
ls -l foo
ls -l foo/file
cat foo/file
cd foo
If the directory `foo' has rights d--x--x--x, the following are
possible if it is known beforehand that `foo' contains an 'r'
readable file named `file':
ls -l foo/file
cat foo/file
cd foo
The following commands fail:
ls foo
ls -l foo

<2.6> How (in)secure is X Windows?
X Windows is the primary software developed by the MIT Athena
project (1983-1991) which was funded by commercial grants
primarily from DEC and IBM to develop
applications to harness the power of networks in enhancing
computational tasks, particularly the human-computer interface.
The software implements a client-server interface to a computer via
graphical windows. In this case the `client' is the application
requesting or utilizing graphical resources (such as windows or a
mouse) and the `server' is the machine that provides them. In many
situations the client is an application program running on the same
machine as the server.
The great utility of X Windows comes from its complete dissociation
of the client and server so that windows may be `broadcast' to a
server at a remote location from the client. Unfortunately this
dynamic power also introduces many deep, intricate, and complicated
security considerations. The primary security and privacy issue
associated with X Windows is that much more sensitive data may be
sent over a network, and over wider regions, than in the case where
the human is situated near the host computer. Currently there is
no encryption of data such as screen updates and keystrokes in X
Windows.
Due to either intentional design decisions or unintentional design
flaws, early versions of the X Window system are extremely
insecure (the decision may have been made not to attempt to
overcome existing vulnerabiliies in the Unix system). Anyone with
an account on the server machine can disrupt that display or read
it electronically based on access to the device unix:0.0 by any
regular user. There are no protections from this type of access
in these versions. The problem arises because the security is
completely based on machine addresses rather than users, such that
any user at a `trusted' machine is himself trusted. Quoting from X
documentation (man Xsecurity):
> Any client on a host in the host access control list is allowed
> access to the X server. This system can work reasonably well in
> an environment where everyone trusts everyone, or when only a
> single person can log into a given machine...This system does not
> work well when multiple people can log in to a single machine and
> mutual trust does not exist.
With the access control list, the `xhost' command may prevent some
naive attempts (i.e. those other than the direct-access unix:0.0
evasion); the syntax as typed on the host machine is ``xhost
+[name]'' where [name] is the domain name or internet address of an
authorized client machine. By default clients running nonlocal to
the host are disabled. Public domain programs to disrupt a display
momentarily (such as 'flip' or slowly mirror the screen image, or
cause pixels to 'melt' down to the bottom) have been circulating on
the internet among hackers for several years and played as pranks
on unsuspecting or inexperienced users. Much more serious security
breaches are conceivable from similar mechanisms exploiting this
inherent weaknesses. (The minimal, easily-bypassed `trusted'
security mode of `xhost' has been jokingly referred to as ``X
Hanging Open, Security Terrible.'').
New versions of the X Window system (X11R5 and higher) by default
make server access as secure as the file system using a .Xauthority
file and 'magic cookies'. Remote machines must have a code in the
.Xauthority file in the home directory that matches the code
allowed by the server. Many older programs and even new
vendor-supplied code does not support or is incompatible with
`magic cookies'. The basic magic cookie mechanism is vulnerable to
monitoring techniques described earlier because no encryption of
keys occurs in transmission. X11R5 also includes other
sophisticated encryption mechanisms. Try `man Xsecurity' to find
out what is supported at your site. Even though improved security
mechanisms have been available in X Windows since ~1990, local
sites often update this software infrequently because installation
is extremely complex.

<2.7> How (in)secure is my email?
By default, not very. The characters that you are reading are
almost certainly encoded in ASCII, the American Standard Code for
Information Interchange that maps alphabetic and symbolic
characters onto numeric codes and vice versa. Virtually every
computer system uses this code, and if not, has ways of converting
to and from it. When you write a mail message, by default it is
being sent in ASCII, and since the standard is virtually
universal, there is no intrinsic privacy. Despite milleniums worth
of accumulated cryptographic knowledge, cryptographic technologies
are only recently being established that afford high priority to
privacy as a primary criteria in computer and network design. Some
potential pitfalls in privacy are as follows:
- The most serious threats are instances of immature or unscrupulous
system operators reading private mail in the `spool files' at a
local site (i.e. at the source or destination of the message),
such as a university.
- System administrators may also release files to law enforcement
agencies, but conventions and protocols for warrants involving
computer searches have still not been strongly established and
tested legally.
- Note that bounced messages go to postmasters at a given site in
their entirety. This means that if you address mail with an
incorrect address it has a good chance of being seen by a human
other than the recipient.
- Typically new user accounts are always set up such that the local
mail directory is private, but this is not guaranteed and can be
overridden.
- Finally, be aware that some mailing lists (email addresses of
everyone on a list) are actually publicly accessable via mail
routing software mechanisms. This `feature' can be disabled.
Most potential compromises in email privacy can be thoroughly
avoided with the use of strong end-to-end cryptography, which has
its own set of caveats (for example, unscrupulous administrators
may still be a threat if the encryption site is shared or
nonlocal). See the sections on ``email privacy'' and ``email
policies.''
_____
<2.8> How am I (not) liable for my email and postings?
As punishment or whatever, your system administrator can revoke
certain `privileges' such as emailing, USENET posting or reading
certain groups, file transferring, remote communications, or
generally any subset of capabilities available from your account.
This all is completely at the discretion of the local administrator
and under the procedures followed at a particular site, which in
many cases are haphazard and crisis-oriented. Currently there are
virtually no widespread, uniform guidelines or procedures for
restricting use to any internet services, and local administrators
are free to make arbitrary decisions on access.
Today punitive measures are regularly applied in various situations.
In the typical scenario complaint(s) reach a system adminstrator
regarding abuses by a user, usually but not necessarily preceded by
complaints to the user in email, regarding that person's
objectionable email or postings. `abusive' posters to USENET are
usually first given admonitions from their system administrators as
urged by others on the `net'. (The debate persists endlessly on
many newsgroups whether this is also used as a questionable means
of attacking or silencing `harmless crackpots' or censoring
unpopular opinions.)
System administrators at remote sites regularly cooperate to
'squelch' severe cases of abuse. In general, however, by tradition
Usenet readers are remarkably tolerant of diverse views and uses of
the system, but a colorful vocabularly of slang helps describe
their alternatives when this patience is sapped: the options
wielded by the individual user are to simply advance to the next
message (referred to as ``hitting the `n' key''), or to `plonk'
annoying posters (according to the Hacker's Dictionary, the sound a
jerk makes at the end of a fall to the bottom of a kill file).
In cases where punitive actions are applied, generally system
administrators are least likely to restrict email. USENET postings
are much more commonly restricted, either to individual users or
entire groups (such as a university campus). Restrictions are most
commonly associated with the following `abuses':
- harassing or threatening notes, `email terrorism'
- illegal uses, e.g. piracy or propagation of copyrighted material
- `ad hominem' attacks, i.e. insulting the reputation of the
poster instead of citing the content of the message
- intentional or extreme vulgarity and offensiveness
- inappropriate postings, esp. binary files in regular groups
`mail-bombing': inundating mail boxes with numerous or massive
files
Major problems originate from lack of distinctions in private and
official email or postings. Most users have internet access via
accounts at businesses or universities and their activities on the
internet can be construed as representative of their parent
organizations. Many people put disclaimers in their `signatures' in
an attempt dissociate their identity and activities from parent
organizations as a precaution. A recent visible political case
involves the privacy of electronic mail written by White House
staff members of the Bush administration. Following are some
guidelines:
- Acquaint yourself with your company or university policy.
- If possible, avoid use of your company email address for private
communication.
- Use a disclaimer.
- Keep a low profile (avoid `flamewars' or simply don't post).
- Avoid posting information that could be construed to be
proprietary or `internal'.

_____
<2.9> How do I provide more/less information to others on my identity?
The public information of your identity and account is mostly
available though the UNIX utility `finger' described above.
- You have control over most of this information with the utility
`chfn', the specifics vary between sites (on some systems use
`passwd -f').
- You can provide unlimited information in the .plan file which is
copied directly to the destination during the fingering.
- A technique that works at some sites allows you to find out who is
'finger'ing you and even to vary the .plan file sent to them.
- Your signature is determined by the environment variable SIGNATURE
- USENET signatures are conventionally stored in the .signature file
in your home directory.
Providing less information on your online identity is more difficult
and involved. One approach is to ask your system adminstrator to
change or delete information about you (such as your full name).
You may be able to obtain access on a public account or one from
someone unrelated to you personally. You may be able to remotely
login (via modem or otherwise) to computers that you are not
physically near. These are tactics for hiding or masking your
online activities but nothing is foolproof. Consult man pages on
the 'chmod' command and the default file mode. Generally, files on
a shared system have good safeguards within the user pool but very
little protection is possible from corrupt system administrators.
To mask your identity in email or on USENET you can use different
accounts. More untraceable are new `anonymous posting' and
remailing services that are very recently being established. See
below.
______
<2.10> Who is my sysadmin? What does s/he know about me?
The requirements and screening for getting a system administration
job (and thereby access to all information on a system) vary widely
between sites and are sometimes frighteningly lax, especially at
universities. Many UNIX systems at universities are largely
managed by undergraduates with a background in computing and often
`hacking'. In general, commercial and industrial sites are more
strict on qualifications and background, and government sites are
extremely strict.
The system adminstrator (root user) can monitor what commands you
used and at what times. S/he may have a record (backups) of files
on your account over a few weeks. S/he can monitor when you send
email or post USENET messages, and potentially read either. S/he
may have access to records indicating what hosts you are using,
both locally and elsewhere. Administrators sometimes employ
specialized programs to track `strange' or `unusual' activity,
which can potentially be misused.
______
<2.11> Why is privacy (un)stable on the internet?
For the numerous reasons listed above, privacy should not be an
expectation with current use of the internet. Furthermore, large
parts of the internet are funded by the U.S. NSF (National Science
Foundation) which places certain restrictions on its use (such as
prohibiting commercial use). Some high-level officials in this and
other government agencies may be opposed to emerging techniques to
guarantee privacy (such as encryption and anonymous services).
Historically the major threats to privacy on the internet have been
local. Perhaps the most common example of this are the widespread
occurrences of university administrators refusing to carry some
portion of USENET newsgroups labelled as `pornographic'. The
`alternative' hierarchy in the USENET system, which has virtually
no restrictions on propagation and new group creation, is
frequently targeted (although this material may appear anywhere).
From the global point of view traffic is generally completely
unimpeded on the internet and only the most egregious offenders
are pursued. For example, verbatim transcriptions of copyrighted
material (such as newspaper or magazine articles) are posted to
USENET with regularity without major consequences (some email
complaints may ensue). More astonishing to some is that currently
significant portions of USENET traffic, and less so internet
traffic, is comprised of sexually-explicit digitized images almost
entirely originating from copyrighted material (newsgroups such as
`alt.sex' regularly have the highest traffic).
______
<2.12> What is the future of privacy on the internet?
Some argue that the internet currently has an adequate or
appropriate level of privacy. Others will argue that as a
prototype for future global networks it has woefully inadequate
safeguards. The internet is growing to become a completely global,
international superhighway for data, and this traffic will
inevitably entail data such as voice messages, postal mail, and
many other items of extremely personal nature. Computer items that
many people consider completely private (such as their local hard
drives) will literally be inches from global network connections.
Also, sensitive industrial and business information is exchanged
over networks currently and this volume may conceivably merge with
the internet.
Most would agree that, for these basic but sensitive uses of the
internet, no significant mechanisms are currently in place to
ensure much privacy. New standards are calling for uniform
introduction of `privacy enhanced mail' (PEM) which uses encryption
technologies to ensure privacy, so that privacy protection is
automatic, and may significantly improve safeguards.
The same technology that can be extremely destructive to privacy
(such as with surreptitious surveilance) can be overwhelmingly
effective in protecting it (e.g. with encryption). Some government
agencies are opposed to unlimited privacy in general, and believe
that it should lawfully be forfeited in cases of criminal conduct
(e.g. court-authorized wiretapping). However, powerful new
technologies to protect privacy on computers are becoming
increasingly popular, provoking some to say that ``the cat is out
of the bag'' and the ``genie can't be put back in the bottle''. In
less idiomatic terms, they believe that the spread of strong
cryptography is already underway will be socially and technically
unstoppable.
To date, no feasible system that guarantees both secure
communication and government oversight has been proposed (the two
goals are largely incompatible). Proposals for ``registration'' of
secret keys (by D. Denning on sci.crypt, for example) have been met
with hot controversy at best and ridicule and derision at worst,
mainly because of concerns for the right to privacy and objections
of inherent feasibility. Electronic privacy issues, and
particularly the proper roles of networks and the internet, will
foreseeably become highly visible and explosive over the next few
years.
ANONYMITY
=========
_____
<3.1> What is `anonymity' on the internet?
Simply stated, anonymity is the absence of identity, the
ultimate in privacy. However, there are several variations on
this simple theme. A person may wish to be consistently
identified by a certain pseudonym or `handle' and establish a
reputation under it in some area, providing pseudo-anonymity.
A person may wish to be completely untraceable for a single
one-way message (a sort of `hit-and-run'). Or, a person may
wish to be openly anonymous but carry on a conversation with
others (with either known or anonymous identities) via an
`anonymous return address'. A user may wish to appear as a
`regular user' but actually be untraceable. Sometimes a user
wishes to hide who he is sending mail to (in addition to the
message itself). The anonymous item itself may be directed at
individuals or groups. A user may wish to access some
service and hide all signs of the association.
All of these uses are feasible on the internet but are currently
tricky to carry out in practice, because of all the tracking
mechanisms inherent to operating systems and network protocols.
Officials of the NSF and other government agencies may be opposed
to any of these uses because of the potential for abuse.
Nevertheless, the inherent facelessness of large networks will
always guarantee a certain element of anonymity.
_____
<3.2> Why is `anonymity' (un)important on the internet?
Anonymity is another powerful tool that can be beneficial or
problematic depending on its use. Arguably absence of
identification is important as the presence of it. It may be the
case that many strong benefits from electronic anonymity will be
discovered that were unforeseen and unpredicted, because true
anonymity has been historically very difficult to establish.
One can use anonymity to make personal statements to a colleague
that would sabotage a relationship if stated openly (such as
employer/employee scenarios). One can use it to pass information
and evade any threat of direct retribution. For example,
`whistleblowers' reporting on government abuses (economic, social,
or political) can bring issues to light without fear of stigma or
retaliation. Sensitive, personal, potentially damaging information
is often posted to some USENET groups, a risky situation where
anonymity allows conversations to be carried on completely
independent of the identities of the participants. Some police
departments run phone services that allow anonymous reporting of
crimes; such uses would be straightforward on the network.
Anonymity can be extremely important and potentially lifesaving
diagnoses and discussions carried out on medical or theurapeutic
newsgroups. Unfortunately, extortion and harassment become more
insidious with assurances of anonymity.
_____
<3.3> How can anonymity be protected on the internet?
The chief means, as alluded to above, are masking identities in
email and posting. However, anonymous accounts (public accounts as
accessable and anonymous as e.g. public telephones) may be
effective as well, but this use is generally not officially
supported and even discouraged by some system adminstrators and NSF
guidelines. The nonuniformity in the requirements of obtaining
accounts at different sites and institutions makes anonymous
accounts generally difficult to obtain to the public at large.
Many communications protocols are inherently detrimental to
anonymity. Virtually every protocol in existence currently
contains information on both sender and receiver in every packet.
New communications protocols will likely develop that guarantee
much higher degrees of secure anonymous communication.
_____
<3.4> What is `anonymous mail'?
One approach to `anonymizing' mail has been to set up an `anonymous
server' that, when activated by email to its address, responds by
allocating and supplying an `anonymous ID' that is unique to the
person requesting it (based on his email address). This will vary
for the same person for different machine address email
originations. To send anonymous mail, the user sends email directed
to the server containing the final destination. The server
`anonymizes' the message by stripping of identification information
and forwards the message, which appears to originate from the
anonymous server only from the corresponding anonymous user id.
This is the `interactive' use of anonymity or pseudonymity
mentioned above.
Another more `fringe' approach is to run a `cypherpunk' remailer
from a regular user account (no root system privileges are
required). These are currently being pioneered by Eric Hughes and
Hal Finney <hal@alumni.caltech.edu>. The operator runs a process on
a machine that anonymizes mail sent to him with certain
characteristics that distinguish it from his regular incoming mail
(typically fields in the header). One has been implemented as a
PERL script running on UNIX. Several of these are in existence
currently but sites and software currently are highly unstable;
they may be in operation outside of system administrator knowledge.
The remailers don't generally support anonymous return addresses.
Mail that is incorrectly addressed is received by the operator.
Generally the user of the remailer has to disavow any
responsibility for the messages forwarded through his system,
although actually may be held liable regardless.
These approaches have several serious disadvantages and weaknesses:
- The anonymous server approach requires maintaining a mapping of
anonymous ID's to real addresses that must be maintained
indefinitely. One alternative is to allow `deallocation' of
aliases at the request of the user, but this has not been
implemented yet.
- Although an unlikely scenario, traffic to any of these sites could
conceivably be monitored from the `outside', necessitating the
use of cryptography for basic protection,.
- Local administrators can shut them down either out of caprice or
under pressure from local, network, or government agencies.
- Unscrupulous providers of the services can monitor the traffic
that goes through them.
- Most remailers currently keep logs that may be inspected.
- The cypherpunk approach tends to be highly unstable because these
operators are basically network users who do not own the
equipment and are accountable to their own system
administrators, who may be unaware of the use and unsympathetic
to the philosophy of anonymity when the operation is discovered,
regarding it as illicit use.
- In all cases, a high degree of trust is placed in the anonymous
server operator by the user.
Currently the most direct route to anonymity involves using SMTP
protocols to submit a message directly to a server with arbitrary
field information. This practice, not uncommon to hackers, and the
approach used by remailers, is generally viewed with hostility by
most system administrators. Information in the header routing data
and logs of network port connection information may be retained
that can be used to track the originating site. In practice, this
is generally infeasible and rarely carried out. Some
administrators on the network will contact local administrators to
request a message be tracked and its writer admonished or punished
more severely (such as revoking the account), all of this actually
happening occasionally but infrequently.
See the sections ``known anonymous mail and posting sites'' and
``responsibilities associated with anonymity''.
_____
<3.5> What is `anonymous posting'?
Anonymous servers have been established as well for anonymous Usenet
posting with all the associated caveats above (monitored traffic,
capricious or risky local circumstances, logging). Make sure to
test the system at least once by e.g. anonymous posting to
misc.test (however some operators don't recommend this because many
sites `autorespond' to test messages, possibly causing the
anonymous server to allocate anonymous IDs for those machines).
See the ``responsibilties associated with anonymous posting''
before proceeding.
Another direct route involves using NNTP protocols to submit a
message directly to a newserver with arbitrary field information.
This practice, not uncommon to hackers, is also generally viewed
with hostility by most system administrators, and similar
consequences can ensue.
See the sections ``known anonymous mail and posting sites'' and
``responsibilities associated with anonymity''.
_____
<3.6> Why is anonymity (un)stable on the internet?
As noted, many factors compromise the anonymity currently available
to the general internet community, and these services should be
used with great caution. To summarize, the technology is in its
infancy and current approaches are unrefined, unreliable, and not
completely trustworthy. No standards have been established and
troubling situations of loss of anonymity and bugs in the software
are prevalent. Here are some encountered and potential bugs:
- One anonymous remailer reallocated already allocated anonymous
return addresses.
- Others passed signature information embedded in messages
unaltered.
- Address resolution problems resulting in anonymized mail bounced
to a remailer are common.
- Forgeries to the anonymous server itself are a problem, possibly
allowing unauthorized users to potentially glean anon ID - email
address mappings in the alias file. This can be remedied with
the use of passwords.
- Infinite mail loops are possible with chaining remailers.
Source code is being distributed, tested, and refined for these
systems, but standards are progressing slowly and weakly. The
field is not likely to improve considerably without official
endorsement and action by network agencies. The whole idea is
essentially still in its infancy and viewed with suspicion and
distrust by many on the internet, seen as illegitimate or favorable
to criminality. The major objection to anonymity over regular
internet use is the perceived lack of accountability to system
operators, i.e. invulnerability to account restrictions resulting
from outside complaints. System adminstrators at some sites have
threatened to filter anonymous news postings generated by the
prominent servers from their redistribution flows. This may only
have the effect of encouraging server operators to create less
characteristically detectable headers. Probably the least
problematic approach, and the most traditional to Usenet, is for
individual users to deal with anonymous mail however they prefer,
e.g. ignoring it or filtering it with kill files.
_____
<3.7> What is the future of anonymity on the internet?
New anonymous protocols effectively serve to significantly increase
safeguards of anonymity. For example, the same mechanism that
routes email over multiple hosts, thereby threatening its privacy,
can also be used to guarantee it. In a scheme called `chaining' an
anonymous message is passed through multiple anonymous servers
before reaching a destination. In this way generally multiple
links of the chain have to be `broken' for security to be
compromised. Re-encryption at each link makes this scenario even
more unlikely. Even more significantly the anonymous remailers
could be spread over the internet globally so that local weaknesses
(such as corrupt governments or legal wiretapping within a nation)
would be more unlikely to sacrifice overall security by message
tracing. However, remailers run by corrupt operators are possible.
The future of anonymous services on the internet is, at this time,
highly uncertain and fraught with peril. While specific groups seem
to benefit significantly from anonymous posting capabilities, many
feel that unlimited newsgroup scope for anonymous posting is a
disruptive and dangerous idea and detracts from discussions in
`serious' groups. The introduction of unlimited group anonymity
may have fundamental repercussions on Usenet conventions and
distribution mechanisms such as moderated and `alt' groups have had
in the past. For example, as part of new group creation, the
charter may specify whether `anonymous' posting is (un)welcome.
Nevertheless, the widespread introduction and use of anonymity may
be inevitable. Based on traffic statistics, anonymous services are
in huge demand. Pervasive and readily available anonymity could
carry significant and unforeseen social consequences. However, if
its use is continued to be generally regarded as subversive it may
be confined to the underground. The ramifications of the
widespread introduction of anonymity to Usenet are still largely
unknown. It is unclear whether it will provoke signficant amounts
of new traffic or, instead of expansion, cause a shift where a
greater portion of existing traffic is anonymized. Conceivably the
services could play a role in influencing future mainstream social
acceptance of Usenet.

EFF was started by the multimillionaire Mitchell Kapor, founder of
Lotus software, and John Barlow, lyricist for the Grateful Dead
rock band. A highly publicized endeavor of the organization
involved the legal defense of Steve Jackson Games after an FBI
raid and an accompanying civil suit (see section on ``Steve
Jackson Games''). The foundation publishes EFF News (EFFector
Online) electronically, send requests to effnews-request@eff.org.
In a letter to Mitchell Kapor from the Chairman of the Subcommittee
with primary jurisdiction over telecommunications policy dated
November 5, 1991, Representative Edward J. Markey complemented
Mitchell Kapor on his ``insights on the development of a national
public information infrastructure'' which ``were appreciated greatly
by myself and the Members of the Subcommittee'' (complete text in

<4.2> Who are Computer Professionals for Social Responsibility (CPSR)?
The Computer Professionals for Social Responsibility have been
working to protect and promote electronic civil liberties issues
since ~1982. The group has three offices (Palo Alto, Cambridge,
Washington, DC) and 20 chapters. It is involved in litigation
against the FBI, The NSA, NIST, the Secret Service and other other
U.S. government agencies to declassify and provide documentation
on issues such as Operation Sundevil, the FBI wiretap proposal,
NSA's interference in crypography, the breakup of the 2600 raid in
Arlington, Va in Nov 1992. Members speak frequently in front on
Congress, state legislators and public utility commissions to
testify on privacy, information policy, computer security, and
caller identification.
CPSR has created an extensive Internet Privacy library available
via FTP, Gopher, WAIS, and email at cpsr.org, currently comprising
the largest collection of privacy documents on the internet. For
more information, anonymous FTP cpsr.org:/cpsr/.

<4.3> What was `Operation Sundevil' and the Steve Jackson Game case?
In the early 1990's a fear spread among U.S. law enforcement
agencies on the illicit activities of `hackers' and
`phreakers' involved in such activities as computer tampering
via modem, credit card fraud, and long-distance call
thievery. (Descriptions of real `hacking' exploits can be
found in the book Cyberpunk by J. Markoff and K. Hafner.)
See ftp.eff.org:/pub/SJG/General_Information/EFFector1.04:
> `Operation Sundevil,' the Phoenix-inspired crackdown of May
> 8,1990, concentrated on telephone code-fraud and credit-card

Massive `show-trials' never materialized, although isolated
instances of prosecution were pursued. The movement reached a
crescendo in Texas with the highly publicized case of illegal
search and seizure involving the Steve Jackson Games company of
Austin Texas on March 1, 1990. From the column GURPS' LABOUR LOST

(A detailed and vivid account of the seizure is documented in the
book ``The Hacker Crackdown'' by Bruce Sterling.) FBI agents
involved in the seizure were named in a civil suit filed on behalf
of Steve Jackson Games by The Electronic Frontier Foundation. See
information on EFF below. From an article by Joe Abernathy in the
Houston Chronicle ~Feb 1, 1993:
> AUSTIN -- An electronic civil rights case against the Secret
> Service closed Thursday with a clear statement by federal
> District Judge Sam Sparks that the Service failed to conduct a
> proper investigation in a notorious computer crime crackdown,
> and went too far in retaining custody of seized equipment.
>
> Secret Service Special Agent Timothy Foley of Chicago, who was in
> charge of three Austin computer search-and-seizures on March 1,
> 1990, that led to the lawsuit, stoically endured Spark's rebuke
> over the Service's poor investigation and abusive computer
> seizure policies. While the Service has seized dozens of
> computers since the crackdown began in 1990, this is the first
> case to challenge the practice.
>
> Sparks grew visibly angry when it was established that the Austin
> science fiction magazine and game book publisher was never
> suspected of a crime, and that agents did not do even marginal
> research to establish a criminal connection between the firm and
> the suspected illegal activities of an employee, or to determine
> that the company was a publisher. Indeed, agents testified that
> they were not even trained in the Privacy Protection Act at the
> special Secret Service school on computer crime.
>
> "How long would it have taken you, Mr. Foley, to find out what
> Steve Jackson Games did, what it was?" asked Sparks. "An hour?

The trial is now recognized as a legal precedent explicitly
guaranteeing protection of electronically stored information under
the Privacy Protection Act, and safeguarding bulletin boards and
electronic mail by federal wiretap laws limiting government
surveillance powers. See the Wall Street Journal, 3/18/93, p. B1,

<4.7> What is U.S. policy on freedom/restriction of strong encryption?
The Clipper announcement says ``we [the Clinton Administration]
understand the importance of encryption technology in
telecommunications and computing'' and specifically addresses the
question, ``would the Administration be willing to use legal
remedies to restrict access to more powerful encryption devices?''
It states that ``The U.S. [is not] saying that `every American, as
a matter of right, is entitled to an unbreakable commercial
encryption product' '' although currently ``the Administration is
not saying, `since [strong] encryption threatens the public safety
and effective law enforcement, we will prohibit it outright' as
some countries have effectively done.'' However, currently no
U.S. laws regulate domestic cryptography use, although the U.S.
International Traffic in Arms Regulations classify cryptographic
devices as `munitions' and regulate export.

CLIPPER
=======
_____
<5.1> What is the Clipper Chip Initiative?
On April 16, 1993 the Clinton Administration announced the Clipper
Chip Directive in a saturated publicity effort (including postings
to Usenet newsgroups by NIST) that introduced the technology and
`proposal' that had been developed in strict secrecy prior to that
date. The `initiative' introduced the Clipper Chip, a high-speed
and `high-security' encryption device with applications in
telephones and other network devices, and the government commitment
to installing it in future select government telephones with
potentially much more widespread penetration (e.g. NREN, commercial
telephones, computers, etc.). The voluntary program seeks to unite
the federal government and private industry ``to improve the
security and privacy of telephone communications while meeting the
legitimate needs of law enforcement'' by use of the chip. Critical
aspects of the directive:
- ``A state-of-the-art microcircuit called the `Clipper Chip' has
been developed by government engineers'', for use in phones with
more power than many commercial encryption devices currently
available. ``The key escrow mechanism will provide Americans with
an encryption product that is more secure, more convenient, and
less expensive than others readily available today.''
- The technology seeks to ``help companies protect proprietary
information, protect the privacy of personal phone conversations
and prevent unauthorized release of data transmitted
electronically'' while preserving ``the ability of federal, state
and local law enforcement agencies to intercept lawfully the
phone conversations of criminals''.
- ``A "key-escrow" system will be established to ensure that the
"Clipper Chip" is used to protect the privacy of law-abiding
Americans.'' Keys are released from the escrow agencies to
``government officials with legal authorization to conduct a
wiretap.''
- ``The two key-escrow data banks will be run by two independent
entities. At this point, the Department of Justice and the
Administration have yet to determine which agencies will oversee
the key-escrow data banks.''
- ``The Attorney General will soon purchase several thousand of the
new devices.'' to ``demonstrate the effectiveness of this new
technology.''
- `Clipper Chip' technology provides law enforcement with ``no new
authorities to access the content of the private conversations of
Americans''.
- The Clipper decision was developed and sanctioned by The National
Security Council, the Justice Department, the Commerce
Department, and ``other key agencies''. ``This approach has
been endorsed by the President, the Vice President, and
appropriate Cabinet officials.''
_____
<5.2> How does Clipper blunt `cryptography's dual-edge sword'?
The Clipper wiretapping initiative refers to `tension between
economic vitality and the real challenges of protecting Americans'
and `previous policies [that] have pitted government against
industry and the rights of privacy against law enforcement.' The
Clipper Initiative attempts to find a compromise in encryption's
``dual-edge sword'' wherein it ``helps to protect the privacy of
individuals and industry, but it also can shield criminals and
terrorists.'' ``The Administration is committed to policies that
protect all Americans' right to privacy while also protecting them
from those who break the law.''
The statement notes that sophisticated encryption technology is
increasingly being used by Americans to ``protect business secrets
and the unauthorized release of personal information'' but also
``by terrorists, drug dealers, and other criminals.'' and declares
that ``We need the "Clipper Chip" and other approaches that can
both provide law-abiding citizens with access to the encryption
they need and prevent criminals from using it to hide their illegal
activities.''
Regarding privacy via encryption vs. wiretapping, the Clipper
announces: ``There is a false `tension' created in the assessment
that this issue is an "either-or" proposition. Rather, both
concerns can be, and in fact are, harmoniously balanced through a
reasoned, balanced approach such as is proposed with the "Clipper
Chip" and similar encryption techniques.''
_____
<5.3> Why are technical details of the Clipper chip being kept secret?
- The algorithm will ``remain classified'' to ``protect the
security of the key escrow system.''
- ``Respected experts from outside the government will be offered
access to the confidential details of the algorithm to assess its
capabilities and publicly report their findings.''
- ``We are willing to invite an independent panel of cryptography
experts to evaluate the algorithm to assure all potential users
that there are no unrecognized vulnerabilities.''
_____
<5.4> Who was consulted in the development of the Clipper chip?
- ``The President has directed early and frequent consultations
with affected industries, the Congress and groups that advocate
the privacy rights of individuals.''
- ``We have briefed members of Congress and industry leaders on the
decisions related to this initiative'' and ``expect those
discussions to intensify''.
_____
<5.5> How is commerical use/export of Clipper chips regulated?
- ``Q. How do I buy one of these encryption devices? A. We expect
several manufacturers to consider incorporating the "Clipper
Chip" into their devices.''
- ``The government designed and developed the key access encryption
microcircuits, but ... product manufacturers ... [buy] the
microcircuits from the chip manufacturer [Mykotronx] that
produces them.''
- The chip's (unspecified) `programming function' ``could be
licensed to other vendors in the future.'' Also, ``We plan to
review the possibility of permitting wider exportability of these
products.''
- ``Case-by-case review for each export is required to ensure
appropriate use of these devices'' fitting in with the existing
program for review of ``other encryption devices.'' ``We expect
export licenses will be granted on a case-by-case basis for U.S.
companies.

<5.7> What are compliments/criticisms of the Clipper chip?
Compliments
----------
- Chip may protect the law abiding citizen's privacy from the casual
snooper.
- Potentially sophisticated and superior algorithm endorsed by the
NSA.
- May establish a new standard whereby companies may be able to
come up with competing pin-compatible chips.
- Potential for encrypting `on top' of the Clipper algorithm.
- May allow diverse law enforcement agency's to retain wiretapping
ability without serious or impossible obstacles.
- May enable broad new traffic analysis by law enforcement agencies.
Criticisms
----------
- Algorithm designed exclusively by the NSA with biased interests.
- Possibly unsophisticated, inferior, or more costly in comparison
with current or emerging technology.
- Compromised keys retroactively weaken all communication ever sent
over the device.
- Key generation techniques are `baroque activities in a vault':
suspicious and unrealistic-sounding.
- Impossible to ensure secrecy of a chip in the face of today's
technology and inevitable intense independent inquiry and
scrutiny, and dependence on it weakens security.
- No specific assurance that key generation is impartial and safe.
- Secrecy of the algorithm prevents serious inquiry and sabotages
trust in the algorithm. No guarantee against `back door'.
_____
<5.8> What are compliments/criticisms of the Clipper Initiative?
Compliments
-----------
- Brings privacy and encryption issues into the limelight.
- Sharpens the public debate on the role, extent, and legitimacy of
wiretapping practices.
- Exposes previously concealed high-level agenda in U.S. government
to manage cryptographic technology.
- Potential new option for individuals and companies interested in
protecting privacy.
- Suggests Clinton administration has strong interest in technology,
reaching compromises, and encouraging competitiveness.
Criticisms
----------
- Evasion of critical aspects (such as key agencies) and
preoccupation with others (references to criminals) ``begs the
question'' of inherent public desireability and support of plan.
- Legality within framework of paramount constitutional guarantees
on freedom of speech and freedom from unreasonable search and
seizure wholly unaddressed.
- Unilaterally imposed, i.e. no involvement from the parties it
purports to represent.
- Funded with taxpayer money with no meaningful public oversight and
scrutiny.
- Represents a fundamental switch in the government's role in
wiretapping from passive to active.
- Potentially criminals won't use the technology and will easily
evade it, while law-abiding citizens will be inconvenienced
and/or sacrifice rights.
- Does not protect the individual from corrupt government officials.
- Secrecy of the algorithm may amount to `security through
obscurity,' i.e. the algorithm security may rely on aspects of
chip operation staying confidential and undiscovered.
- Government appears to be colluding with private companies and
using leverage to intentionally create a monopoly.
- Possibility of taxpayer funds effectively subsidizing chip sales
not addressed.
- Secrecy of the chip design prevents inquiries into its precise
security.
- ``government engineers'' in competition with private industries,
with special favoritism in policies of the Clinton
administration.
- may require new vast and superfluous government bureacracies.
_____
<5.9> What are compliments/criticisms of the Clipper announcement?
Compliments
-----------
- Shows unequivocal commitment to wiretapping drug dealers,
criminals, and terrorists.
- Publicizes previously secret development and processes regarding
Clipper in particular and cryptography in general.
- Well publicized within some circles. Usenet press release
unprecedented and sophisticated.
- Shows Clinton administration commitment to developing national
policies on `information infrastructure' and the intrinsic role
of encryption technology.
- Masterpiece of propaganda for study by future generations.
Criticisms
----------
- States that Clipper is better than many encryption technologies
available today but does not indicate that many are recognized to
be weak and new and more powerful technologies are already under
development.
- Vague on critical aspects such as who the key escrow agencies are.
- Appears to assume that Americans wish to preserve wiretapping
capabilities by law enforcement agencies in the face of new
unbreakable encryption technologies.
- Specifically does not commit to freedom of encryption and hints
that failure of Clipper-style approaches may lead to restrictions
on strong cryptography.
- Gives the impression that Congress and private industry was
involved when their participation is minimal to nonexistent.
- Authoritarian, dictatorial, and Orwellian undertones.
- Evades mention of the NSA's specific involvement.
- Refers to the chip as `state of the art' without evidence.
- Refers to ``drug dealers, criminals, and terrorists'' with terms
such as `alleged,' `suspected,' `reputed,' and `accused'
conspicuously absent.
- Does not specifically commit to unrestrained public policy review
and appears to evade it.
- Evades mention of the history of the plan and erroneously implies
that Clinton administration involvement is primary.

<5.10> Where does Clipper fit in U.S. cryptographic technology policy?
The Clipper chip is part of a large-scale plan that involves ``the
creation of new products to accelerate the development and use of
advanced and secure telecommunications networks and wireless
communications links'' utilizing the chip.
- ``we [of the Clinton Administration] understand the importance of
encryption technology in telecommunications and computing and are
committed to working with industry and public-interest groups to
find innovative ways to protect Americans' privacy, help
businesses to compete, and ensure that law enforcement agencies
have the tools they need to fight crime and terrorism.''
- ``The President has directed government agencies to develop a
comprehensive policy on encryption'' and ``explore new approaches
like the key-escrow system'' which ``is just one piece of what
must be the comprehensive approach to encryption technology,
which the Administration is developing.''
- The `broad policy review' will also address the role of
cryptography in ``the development of a National Information
Infrastructure or `information superhighways''' and consider
``the need of U.S. companies to manufacture and export high
technology products.''
- ``The Federal Government must act quickly to develop consistent,
comprehensive policies regarding its use'' and ``as we carry out
our review of encryption policy'' the ``on-going discussions with
Congress and industry on encryption issues'' are expected to
``intensify.''

From the RIPEM FAQ by Marc VanHeyningen
<mvanheyn@whale.cs.indiana.edu> on news.answers:
> RIPEM is a program which performs Privacy Enhanced Mail (PEM)
> using the cryptographic techniques of RSA and DES. It allows
> your electronic mail to have the properties of authentication
> (i.e. who sent it can be confirmed) and privacy (i.e. nobody can
> read it except the intended recipient.)
>
> RIPEM was written primarily by Mark Riordan
> <mrr@scss3.cl.msu.edu>. Most of the code is in the public domain,
> except for the RSA routines, which are a library called RSAREF
> licensed from RSA Data Security Inc.
>
> RIPEM is available via anonymous FTP to citizens and permanent
> residents in the U.S. from rsa.com; cd to rsaref/ and read the
> README file for info.
>
> RIPEM, as well as some other crypt stuff, has its `home site' on
> rpub.cl.msu.edu, which is open to non-anonymous FTP for users in
> the U.S. and Canada who are citizens or permanent residents. To
> find out how to obtain access, ftp there, cd to pub/crypt/, and

<6.3> What is the cypherpunks mailing list?
Eric Hughes <hughes@toad.com> runs the `cypherpunk' mailing list
dedicated to ``discussion about technological defenses for privacy
in the digital domain.'' Send email to
cypherpunks-request@toad.com to be added or subtracted from the
list. From the charter:
> The most important means to the defense of privacy is encryption.
> To encrypt is to indicate the desire for privacy. But to encrypt
> with weak cryptography is to indicate not too much desire for
> privacy. Cypherpunks hope that all people desiring privacy will
> learn how best to defend it.

<6.7> How can I run an anonymous remailer?
Cypherpunk remailer source is at soda.berkeley.edu in the
/pub/cypherpunks directory. It's written in PERL, and is
relatively easy to install (no administrative rights are required)
although basic familiarity with UNIX is necessary. Karl Barrus
<elee9sf@menudo.uh.edu> has more information and modifications.
Also, most remailer operators mentioned above are amenable to
discussing features, problems, and helping new sites become
operational. Address all points in the section ``responsibities of
anonymous use'' in this document prior to advertising your service.
You should be committed to the long-term stability of the site and
avoid running one surreptitiously.

_____
<7.1> What is ``digital cash''?
With digital encryption and authentication technologies, the
possibility of a widespread digital cash system may someday be
realized. A system utilizing codes sent between users and banks
(similar to today's checking system except entirely digital) may
be one approach. The issues of cryptography, privacy, and
anonymity are closely associated with transfer of cash in an
economy. See the article in Scientific American by David Chaum
(~Dec.1992).
An experimental digital bank is run by Karl Barrus
<elee9sf@Menudo.UH.EDU> based on suggestions by Hal Finney on the
cypherpunks mailing list. To use the server send mail to
elee7h5@rosebud.ee.uh.edu message with the following text:
::
command: help
user@host
where `user@host' is your email address.
_____
<7.2> What is a ``hacker'' or ``cracker''?
These terms arouse strong feelings by many on their meaning,
especially on the internet. In the general news media in the past
a person who uses computers and networks to malicious ends (such as
breaking into systems) has been referred to as a hacker, but most
internet users prefer the term ``cracker'' for this. Instead, a
``hacker'' is perceived as a benign but intensely ambitious,
curious, and driven computer user who explores obscure areas of a
system, for example---something of a proud electronic pioneer and
patriot. This is the sense intended in this document. See also
the ``Hacker's Dictionary'' and the FAQ `alt-security-faq'.
_____
<7.3> What is a ``cypherpunk''?
From the charter of the cypherpunk mailing list:
> Cypherpunks assume privacy is a good thing and wish there were
> more of it. Cypherpunks acknowledge that those who want privacy
> must create it for themselves and not expect governments,
> corporations, or other large, faceless organizations to grant
> them privacy out of beneficence. Cypherpunks know that people
> have been creating their own privacy for centuries with whispers,
> envelopes, closed doors, and couriers. Cypherpunks do not seek
> to prevent other people from speaking about their experiences or
> their opinions.
See information on the cypherpunk mailing list below.
See also the CryptoAnarchist Manifesto and the Cryptography Glossary
in soda.berkeley.edu:/pub/cypherpunks.
_____
<7.4> What is `steganography' and anonymous pools?
Closely associated with encryption is `steganography' or the
techniques for not only pursuing private (encrypted) communication
but concealing the very existence of the communication itself.
Many new possibilities in this area are introduced with the
proliferation of computer technology. For example, it is possible
to encode messages in the least-significant bits of images,
typically the most 'noisy'. In addition, when such an item is
posted in a public place (such as a newsgroup), virtually
untraceable communication can take place between sender and
receiver. For steganographic communications in the electronic
realm one another possibility is setting up a mailing list where
individual messages get broadcast to the entire list and individual
users decode particular messages with their unique key. An
anonymous pool has been set up by Miron Cuperman
(miron@extropia.wimsey.com) for experiments. Send email to
<pool0-request@extropia.wimsey.com> with one of the following
commands in the subject line:
subscribe
unsubscribe

_____
<7.5> What is `security through obscurity'?
`Security through obscurity' refers to the attempt to gain
protection from system weaknesses by hiding sensitive information
or programs relating to them. For example, a company may not make
public information on its software's encryption techniques to evade
`attacks' based on knowledge of it. Another example would be
concealing data on the existence of security holes or bugs in
operating systems. Or, some reliance may be made on the fact that
some standard or mechanism with potential problems is serious
because they are ``not widely known'' or ``not widely used.'' This
argument is occasionally applied to mechanisms for email and Usenet
posting `forgery'. `Security through obscurity' is regarded as a
very feeble technique at best and inappropriate and ineffective at
worst (also called the ``head-in-the-sand approach''). See the FAQ
for alt.security.
Some remarks of John Perry Barlow, cofounder of the Electronic
Frontier Foundation, directed to NSA agents at the First
International Symposium on National Security & National
Competitiveness held in McLean, Virginia Dec. 1, 1992:
> Digitized information is very hard to stamp classified or keep
> contained. ... This stuff is incredibly leaky and volatile. It's
> almost a life form in its ability to self-propagate. If
> something hits the Net and it's something which people on there
> find interesting it will spread like a virus of the mind. I
> believe you must simply accept the idea that we are moving into
> an environment where any information which is at all interesting
> to people is going to get out. And there will be very little
> that you can do about it. This is not a bad thing in my view,
> but you may differ...
_____
<7.6> What are `identity daemons'?
RFC-931 describes a protocol standard that allows UNIX programs to
query a remote user's login name after connection to a local
communication socket (a connection of this type is established
during FTP and TELNET sessions, for example). The standard is not
widely supported, perhaps 10% of internet sites currently implement
it but the number is increasing. The mechanism is detrimental to
anonymity. Regular users cannot disable it but system
adminstrators can circumvent it. This standard may represent a

<7.7> What standards are needed to guard electronic privacy?
Remailing/Posting
-----------------
- Stable, secure, protected, officially sanctioned and permitted,
publicly and privately operated anonymous servers and hubs.
- Official standards for encryption and anonymity in mail and USENET
postings.
- Truly anonymous protocols with source and destination information
obscured or absent and hidden routing mechanisms (chaining,
encrypted addresses, etc.)
- Standards for anonymous email addressing, embedding files, and
remailer site chaining.
General
-------
- Recognition of anonymity, cryptography, and related privacy
shields as legitimate, useful, desirable, and crucial by the
general public and their governments.
- Widespread use and implementation of these technologies
by systems designers into
hardware, software, and standards, implemented `securely,'
`seamlessly,' and `transparently'.
- General shift of use, dependence, and reliance to means other than
wiretapping and electronic surveillance by law enforcement
agencies.
- Publicity, retraction, and dissolution of laws and government
agencies opposed to privacy, replaced by structures dedicated to
strengthening and protecting it.

<8.1> What is the background behind the Internet?
The article ``Internet'' in Fantasy and Science Fiction by Bruce
Sterling <bruces@well.sf.ca.us> contains general and nontechnical
introductory notes on origins of the Internet, including the role
of the RAND corporation, the goal of network resilience in face of
nuclear attack, MIT, UCLA, ARPANET, TCP/IP, NSF, NREN, etc.:
> ARPANET itself formally expired in 1989, a happy victim of its
> own overwhelming success. Its users scarcely noticed, for
> ARPANET's functions not only continued but steadily improved.
> The use of TCP/IP standards for computer networking is now
> global. In 1971, a mere twenty-one years ago, there were only
> four nodes in the ARPANET network. Today there are tens of
> thousands of nodes in the Internet, scattered over forty-two
> countries, with more coming on-line every day. Three million,
> possibly four million people use this gigantic
> mother-of-all-computer-networks.
>
> The Internet is especially popular among scientists, and is
> probably the most important scientific instrument of the late
> twentieth century. The powerful, sophisticated access that it
> provides to specialized data and personal communication has sped
> up the pace of scientific research enormously.
>
> The Internet's pace of growth in the early 1990s is spectacular,
> almost ferocious. It is spreading faster than cellular phones,
> faster than fax machines. Last year the Internet was growing at
> a rate of twenty percent a *month.* The number of `host'
> machines with direct connection to TCP/IP has been doubling
> every year since 1988. The Internet is moving out of its
> original base in military and research institutions, into
> elementary and high schools, as well as into public libraries
> and the commercial sector.

<8.2> How is Internet `anarchy' like the English language?
According to Bruce Sterling <bruces@well.sf.ca.us>:
> The Internet's `anarchy' may seem strange or even unnatural, but
> it makes a certain deep and basic sense. It's rather like the
> `anarchy' of the English language. Nobody rents English, and
> nobody owns English. As an English-speaking person, it's up
> to you to learn how to speak English properly and make whatever
> use you please of it (though the government provides certain
> subsidies to help you learn to read and write a bit).
> Otherwise, everybody just sort of pitches in, and somehow the
> thing evolves on its own, and somehow turns out workable. And
> interesting. Fascinating, even. Though a lot of people earn
> their living from using and exploiting and teaching English,
> `English' as an institution is public property, a public good.
> Much the same goes for the Internet. Would English be improved
> if the `The English Language, Inc.' had a board of directors
> and a chief executive officer, or a President and a Congress?
> There'd probably be a lot fewer new words in English, and a lot
> fewer new ideas.

Hopefully you have benefitted from this creation, compilation, and
condensation of information from various sources regarding privacy,
identity, and anonymity on the internet. The author is committed
to keeping this up-to-date and strengthening it, but this can only
be effective with your feedback, especially on sections of
interest. In particular, the following items are sought:
- Short summaries of RFC documents and other references listed,
esp. CPSR files.
- More data on the specific uses and penetration of RFC-931.
- Internet traffic statistics. How much is email? How much
USENET? What are the costs involved?
- Famous or obscure examples of compromised privacy
on the internet.
- FTP site for the code (NOT the code) to turn the .plan file into a
named pipe for sensing/reacting to remote `fingers'.
- X Windows, EFF, CPSR FAQhood in news.answers.
Commerical use of this document is negotiable and is a way for the
author to recoup from a significant time investment. Email feedback
