- The group would undoubtedly be charged with criminal conspiracy
- in addition to violating the Munitions and Foreign Armaments
- act, in addition to whatever other trumped-up charges could be
- applied. I would guess, looking at the typical punishment
- meted out in the U.S. Code you would be threatened with 20-30
- years in prison and a half-a-million dollar fine, each.
- Consider this the U.S. government's contribution to your
- academic freedom and creative state-of-mind. :-)

- However, take heart, the Internet is already the most immediate
- and powerful voice of free technical international exchange on
- the planet. Given that the people in all countries linked by
- it are at least as smart on average as U.S. and Canadian crypto
- researchers, and that crypto research in general requires no
- vast infrastructure (unlike the superconducting supercollider,
- for example), just sharing our thoughts on sci.crypt and
- international conferences such as EuroCrypt, will soon
- guarantee that the crypto sophistication outside North America
- will surpass that on the inside.
-
- The NSA will slowly become just a poor technical arm of the
- FBI, since only citizens in _this_ country will be stuck with
- crypto/telephony systems that can be broken...
-
- (Stuck on citizens and industry that don't have the technical
- expertise to read and understand sci.crypt, that is. ;-))
-
- For all you crackers out there -- this is a dream manifesto:
- the "official NSA/FBI approved" industrial crypto and digital
- telephony systems will be delayed and use less effective crypto
- systems than available in the E.C. or the Pacific Rim world.
- That undoubtedly will mean there will be holes that can be
- exploited by the crackers, while the cracker _themselves_ can
- use wholly effective cryptographic means picked up at any
- international souk to conspire and pool their computational and
- analytic skills.
-
- What can you do to resolve these issues?
-
- I've already internationally posted DES and RSA source to this
- group; I'm writing a new short article describing a disciplined
- approach to combining conventional crypto systems in a way that
- each "hide" each others canonical weaknesses: a method that I'm
- calling "laminated" cryptography.
-
- By all of us amateurs and private industry professionals
- working as hard as we can to create and disseminate crypto
- information, I hope that we can stimulate the immune systems of
- our FBI/NSA to become innovative on their own and figure out
- how to fulfill their statutory missions without stifling
- cryptographic/information-theoretic research. But I'm not
- optimistic.
-
- Demanding innovation from any bureaucracy with its built in
- "smoothing function" is always difficult, but with the NSA/FBI
- it is going to be exponentially hard because of the lack of
- effective oversight by the citizens they serve.
-
- I'd have posted this to sci.crypt.politics, but, alas, the
- technical and political issues seem utterly conflated. :-(
