>||| Commerce Department issues new rules for cryptography export |||
>The new regulations governing crypto export are dubbed EAR (Export
>istration Regulations) -- for the hypertext version  thank John
><firstname.lastname@example.org>: the full text  weighs in at 109K. EAR replaces the
>(International Trafficking in Arms Regulations), administered by the
>Department since the early days of the Cold War. The revised
>contain the same "prior restraint" features that got the ITAR declared
>unconstitutional in Federal court in December . The plaintiff in
>case, Daniel Bernstein, has requested  that the government delay im-
>plementing the new rules until a judge rules on their
>if such a delay is not stipulated  then Bernstein will ask for an
>junction. Bernstein is scheduled to begin teaching a class on
>next Monday 1/13/97, and unless the EAR is delayed he could face
>tion if he posts course materials on the Internet.
>Posters to the Cryptography mailing list, particularly Lucky Green
><email@example.com>, have uncovered the following wrinkles in the new
>regulations. In each post Green cautions "IANAL" (I am not a lawyer),
>and I hereby do the same.
>o The EAR bans the export of certain non-crypto data security software
> such as virus checkers and firewalls. Any U.S. company offering a
> virus checker for download on its Web or FTP site is probably in vio-
> lation of the EAR.
>o Key-recovery provisions stipulate that keys be made available without
> knowledge of the user. Some suggested key-recovery schemes would
> the user when keys were requested; such schemes are presumably now
> of bounds.
>o The new rules forbid U.S. entites from entering into foreign
> for cryptographic work, closing the loophole long used by C2 and
> . The prohibition against "financing, contracting, service,
> transportation, freight forwarding, or employment" can be found about
> halfway down ; search for "General Prohibition Seven."
>||| The crypto debate in a nutshell |||
>Carl M. Ellison <firstname.lastname@example.org> has put considerable thought into
>ing the debate over cryptography, and his distillation of the central
>issue  is one of the more clearheaded pieces of writing you'll find
>anywhere in this emotional landscape. As Ellison sees it, a fundamental
>question goes unaddressed by either side: do citizens of a country have
>a right to attempt to achieve privacy from their government, or should
>they be forced to submit to covert surveillance? Both sides vigorously
>behave as if the answer to this question were obvious, but their
>answers are diametrical opposites.
>If anyone wishes to contribute an analysis based on quantum
>ity, I'll publish any such essay that that illuminates the debate.
>||| Information warfare: studies military and civilian |||
>A panel security experts convened by the Defense Department recommended
>spending an additional $3 billion over the next 5 years to stiffen U.S.
>telecom/computing infrastructure resistance to an anticipated
>Pearl Harbor." The story appeared in the Wall Street Journal for
>you will need to sign up for a trial subscription to follow this link
>The report is bluntly worded and calls the current military
>security practices and assumptions "ingredients in a recipe for a
>security disaster." (Military spokesmen demur, anxious not to
>outside kibbutzing on their current $1.6B annual info-security budget.)
>The task force's chairman, Duane Andrews, noted in an interview that
>law forbids the military from implementing strong countermeasures, such
>as a program to "repel and pursue" those who try to hack into DoD com-
>puter systems. He wants the law changed so the Pentagon can respond by
>injecting attackers' computers with "a polymorphic virus that wipes out
>the system, takes it down for weeks." Fans of due process will be grat-
>ified that there is no report of such a technique (William Gibson
>it "ice") being mentioned in the study proper.
>Andrews added, "Most of the stuff in [the report] is a message to
>try, too. A large international bank has exactly the same problems and
>challenges as the Defense Department."
>Dan Farmer <email@example.com> would probably agree. The man whose 1994
>release of the SATAN security-scanning program  got him dismissed
>from SGI has recently published  the results of a study in which he
>examined the vulnerability of 1700 high-profile, commerce-oriented Web
>sites. These are the kind of sites we'd like to believe are exquisitely
>sensitized to security concerns. Farmer did nothing illegal, he claims:
>"I barely electronically breathed on these hosts." Nevertheless he
>over 60% of the sites vulnerable to compromise or destruction by simple
>and widely known breakin techniques. He estimates that a further 10% to
>20% would yield to more sophisticated attacks.
>Thanks to Dan Kohn <firstname.lastname@example.org> for pointing me to the military
>study and to Keith Bostic <email@example.com> for the civilian.
>||| RSA challenges the Net to break 56-bit DES |||
>RSA wants to demonstrate the relative vulnerability of the 56-bit Data
>Encryption Standard (approved for export, with key recovery under the
>new EAR) against the company's own RC5 Symmetric Block Cipher
>RSA will award $10,000 to the first sender of the secret DES key used
>to encode a target "ciphertext," which they will post to their Web site
>on 1/27. At the same time the company will initiate 12 shots at RC5,
>RSA's block cipher (summary at , details at ). Participants are
>challenged to discover RC5 keys ranging in length from 40 to 128 bits
>in steps of 16 bits; prizes offered range from $200 to several thousand
>dollars based on key length.
>Peter Trei <firstname.lastname@example.org> has been working on code to make it easy
>for PC users across the Net to participate in these challenges. He
>in a work-in-progress reports to the Cryptography list that code should
>be available by mid-to-late January.
>||| Three ways to fight email spam, and two asides |||
>If you use email you're in no doubt that spam is on the rise. Zero Junk
>Mail Inc.  offers the service of removing your name from the
>lists; they claim they can reduce your junk mail by 75% within a year.
>The catch is that even those spam practitioners who follow the recom-
>mendations of the Direct Marketing Association by offer their victims a
>way off their lists may not accept third-party "unsubscribe" requests.
>Media Daily spotlights ZJM and two other antispam products at .
>TSW offers a $10 shareware package called eFilter  for PCs that
>views the email waiting on your POP server and deletes messages
>ing keywords that you specify, leaving a log for your examination. The
>drawback here is that it only works for repeat offences from a
>spammer. Don't know about you, but the bulk of the spam I receive is
>Rosalind Resnick <email@example.com>, one of the early practi-
>tioners who helped us all to figure out how online marketing could be
>done within the best traditions of the Net, may have invented a better
>way. Her NetCreations site offers a service  at which users can
>up for online solicitations that they actually want to read. At the
>time of my visit the site listed 1327 areas of interest. I sincerely
>hope that the online direct-marketing community flocks to Resnick's
>service and she becomes very rich. The gloomy alternative is spelled
>out by John C. Dvorak <firstname.lastname@example.org> in the December 1996 Boardwatch
>> In direct mail, you lose money if you solicit people who do not want
>> to buy. So you are careful [to target your messages] or you go broke.
>> With email marketing, this natural selection process will never hap-
>> pen... Why should anyone care about targeting when mail is free?...
>> I wonder what we will do when thousands of spams show up in our email
>> each and every day?
>Aside (1): speaking of early practitioners, I recently recrossed the
>traces of Christopher Locke <email@example.com>, whose writings while
>he was at Mecklermedia, in 1994, laid the foundations for my thinking
>about online marketing. Locke is now VP Business Development and web-
>master at Displaytech , a Colorado manufacturer of "portable
>that don't suck." His breathlessly postmodern press release begins:
>> Displaytech makes miniature high-resolution full-color multi-hyphen-
>> modified displays that fit on a computer chip the size of your thumb-
>> nail. magnifying the image yields a virtual screen as good as any
>> desktop monitor. the tech is fast and small enough so that it can
>> be embedded in head mounted color displays that don't make the people
>> wearing them look as if they just landed from mars.
>Aside (2): speaking of Boardwatch magazine, their third quarterly guide
>to U.S. ISPs is now available; it contains the best answer, in
>detail, that I have ever read to the question: What is the Internet?
>article, written by editor Jack Rickard, like the rest of the ISP guide
>is available on the Web  (53K), but I suggest you obtain  the
>trees edition and give it close study.
>||| Will Compaq acquire Digital? |||
>A rumor to this effect was carried in ComputerGram some time before
>If you have a subscription (I don't, myself) you can follow this link
>Rumors over the last six months have suggested that Compaq, desiring to
>be taken seriously as an enterprise-capable computer company, wanted to
>Digital's systems support business. These talks came to a halt and were
>renewed recently, again according to rumor, this time with the aim of a
>full acquisition. ComputerGram runs through a money exercise to
>that at current stock prices such a deal would make sense even if
>closed down the Alpha chip business and wrote it off.
>||| Followups |||
> || IAHC domain-name plan is drawing fire ||
> TBTF for 12/24/96 
> TechWire reports  that opposition is mounting to the draft Inter-
> national Ad Hoc Committee plan for extending the number of top-level
> domains. Complaints include the 60-day waiting period for new names
> and the proposed lottery system for choosing the initial suppliers.
> The president of one Web-design firm, who has invested to develop
> the unofficial top-level name .web, says he is "unwilling to roll
> the dice" on this sunk cost. An overall criticism is that the com-
> mittee's recommendations are unbalanced, favoring large tradename
> holders at the expense of smaller players -- a charge that is fre-
> quently levelled against InterNIC, which currently holds a monopoly
> in granting top-level names.

> Netcom, one of the largest U.S. ISPs, has signed with AimQuest

> one of several sources of "virtual tunneling" among a network of ISPs
> to extend the geographical reach of all the members.

> || Microsoft backpedals on license wording ||
> TBTF for 12/14/96 
> Microsoft will reword its Java SDK license agreement to assuage user
> fears that their applications might be legally bound to run
> on Microsoft's Java Virtual Machine. According to TechWire , some
> user organizations have told their engineers to de-install the Visual
> J++ Java development environment, worried that under deadline
> engineers might succumb to the temptation offered by existing ActiveX

> TBTF for 9/23/96 
> Preparations continue apace for the first refereed conference on

> using DigiCash's ecash .
> Below is an excerpt from a Hettinga rant in which he expounds, with
> storied prolixity, on the reasons why you must attend this
> Reason number 8:
> > FC97 is chance for those of us who only know each other on the net
> > to actually meet face to face and start to develop the kind of per-
> > sonal relationships and trust we'll all need to create the future
> > of finance on the Internet... And, while the whole point to finan-

> > for financial relationships, much less regulation, there's still,
> > currently, more bandwidth in a conversation on an Anguillan beach
> > to develop that trust relationship than there is anywhere on the

> going I'll see you on the beach in February.

>||| Pretty bad publicity |||
>Herewith two examples of corporate moves that the PR firms of PGP, Inc.
>and Viacom should have warned their clients away from.

> calling Very Good Privacy. He received a complaining letter from PGP,
> Inc. and was casting about for a new name. Posting a call for alter-
> natives to the cypherpunks mailing list (subject: "The product

>||| The Saturn-like object near Comet Hale-Bopp |||
>Comet Hale-Bopp is now separating from the sun in the morning sky and
>is expected to make a spectacular showing over much of the world in
>March and April. It may even be The Comet of the Century, though astro-
>nomers are touchingly reticent to say so after the over-hyped and dis-
>appointing displays of Kohoutek in 1974 and Halley in 1986.
>Riley Rainey <email@example.com> sent along a fine piece (titled
>Bits from the Astronomical Front) regarding the comet and the furor
>erupted around it last November. Three days later the Red Rock Eater
>Service carried an account of the affair by Paul Saffo, emphasizing
>the Internet can be used to quash a rumor that happens not to be true,
>well as it can be used to fan one.
>Last November an amateur astronomer named Chuck Shramek took a photo-
>graph that had him puzzled: it seemed to show a "Saturn-like object" in
>the field of view with the comet. Shramek could not find any
