Terror groups hide behind Web encryption
Hidden in the X-rated pictures on several
pornographic Web sites and the posted comments
on sports chat rooms may lie the encrypted
blueprints of the next terrorist attack
against the United States or its allies. It
sounds farfetched, but U.S. officials and
experts say it's the latest method of
communication being used by Osama bin Laden
and his associates to outfox law enforcement.
Bin Laden, indicted in the bombing in 1998
of two U.S. embassies in East Africa, and
others are hiding maps and photographs of
terrorist targets and posting instructions
for terrorist activities on sports chat
rooms, pornographic bulletin boards and
other Web sites, U.S. and foreign officials
say.

Bell Labs cryptologist sees digital signature flaw, fix
A SCIENTIST AT Bell Labs, the research and development
wing of Lucent Technologies, has discovered a flaw in
the Digital Signature Algorithm (DSA) that could affect
the integrity of secure transactions on the Internet
and adversely impact VPNs (virtual private networks),
online shopping, and online financial transactions.
Daniel Bleichenbacher, a member of Bell Labs'
Information Sciences Research Center, discovered a
glitch in the random number generation technique used
with the DSA, according to the company in a statement.
He learned that the DSA's random number generator was
biased and was twice as likely to pick a set of numbers
from one range than from another.  The U.S. National
Security Agency designed DSA and it is one of three
authentication algorithms approved for generating and
verifying digital signature under the Digital Signature
Standard.
