Abstract. In this paper we analyse the security of a new key exchange
protocol proposed in [3], which is based on mutually learning neural 
networks. This is a new potential source for public key cryptographic 
schemes which are not based on number theoretic functions, and 
have small time and memory complexities. In the first part of the paper 
we analyse the scheme, explain why the two parties converge to a 
common key, and why an attacker using a similar neural network is 
unlikely to converge to the same key. However, in the second part 
of the paper we show that this key exchange protocol can be broken 
in three different ways, and thus it is completely insecure.

Open-Source Fight Flares At Pentagon Microsoft Lobbies Hard Against Free Software

Open-Source Fight Flares At Pentagon
Microsoft Lobbies Hard Against Free Software
http://www.washingtonpost.com/wp-dyn/articles/A60050-2002May22.html

By Jonathan Krim
Washington Post Staff Writer
Thursday, May 23, 2002; Page E01

Microsoft Corp. is aggressively lobbying the Pentagon to squelch its
growing use of freely distributed computer software and switch to
proprietary systems such as those sold by the software giant,
according to officials familiar with the campaign.

In what one military source called a barrage of contacts with
officials at the Defense Information Systems Agency and the office of
Defense Secretary Donald H. Rumsfeld over the past few months, the
company said open source software threatens security and its
intellectual property.

But the effort may have backfired. A May 10 report prepared for the
Defense Department concluded that open source often results in more
secure, less expensive applications and that, if anything, its use
should be expanded.

Banning open source would have immediate, broad, and strongly
negative impacts on the ability of many sensitive and security-focused
DOD groups to protect themselves against cyberattacks, said the
report, by Mitre Corp.

text deleted

Microsoft also said open-source software is inherently less secure
because the code is available for the world to examine for flaws,
making it possible for hackers or criminals to exploit
them. Proprietary software, the company argued, is more secure because
of its closed nature.

A master of the security half-truth chimes in...

I've never seen a systematic study that showed open source to be more
secure, said Dorothy Denning, a professor of computer science at
Georgetown University who specializes in information warfare.



John Stenbit, an assistant secretary of defense and the Defense
Department's chief information officer, said Microsoft has said using
free software with commercial software might violate the
intellectual-property rights of companies such as Microsoft. Stenbit
said the issue is legally murky.

much deleted

Stenbit said the debate is academic and that what matters is how
secure a given piece of software is. To that end, the Defense
Department is now prohibited from purchasing any software that has not
undergone security testing by the NSA. Stenbit said he is unaware of
any open-source software that has been tested.

This should present no problem for open source software.  No purchase takes 
place since the software is free by definition.

 I think you'd have to do it in reverse to stand a chance if you

Self-signed and CA x.509 certificates cannot be used in Outlook
even when they are added to the Trusted Root CA's.

Apparently Outlook is able to distinguish between these and
CA-issued x.509 certificates.

Future of commercial PGP? [was NAI gets out the DMCA stick]

2002-05-23 Thread stoat2k

As mentioned by others, NAI currently seems bent on discouraging proliferation of 
existing PGP desktop packages.  Part of this seeming strategy includes a refusal to 
sell any further licenses for commercial PGP 7.X.

Strangely, the June 2002 PC Magazine (at least where I live) includes a CDROM 
containing McAfee PGP 6.5.8.  The CDROM pop-up says the software is worth $XX, so 
I assume this is the commercial version or some variant thereof.  (I haven't tried 
installing it since I won't have suitable sacrificial machine for a few days.)

Strange timing.  Perhaps an earlier contractual arrangement had to be honored.

As far as a future commercial version of PGP, at the moment this seems to be the 
McAffee E-Business Server and Client, which appear to be the successors to PGP Server 
and PGP Desktop, respectively.  The desktop product now appears to depend on the 
presence of a Server instance in order to function.  I believe the Server licenses for 
~$2K US.

Reference:  http://www.mcafeeb2b.com/products/ebusiness.asp

Puzzling that these products are not being more actively trumpeted as the worthy 
successors to PGP.  Or have I missed a recent marketing campaign?

If there are whitepapers describing a migration strategy, or the technical details of 
E-Business Client/Server interaction, I am not aware of them.  However, I'd be happy 
to be proven wrong on that point, or further enlightened regarding any of the above.

 This won't achieve the desired effect because it will just destroy the
 S/MIME trust mechanism.  S/MIME is based on the assumption that all
 CAs are trustworthy.

Which is, of course, a major flaw.

S/MIME is of some value for internal corporate email for companies who can
run their own CA. (The sort of people who used to be Xcert's customers.)

S/MIME is of very little value outside of a closed intranet environment,
for the simple reason that public CAs are mostly incompetent,
untrustworthy, or both.

 This is a fairly accurate description of the situation, but

Yes, [1] understands its importance. I think you overestimate the amount
of effort put forth by [1] to spread the Word, though. While
evangelizing strong crypto might be second-nature to a cypherpunk, the
other members of [1] are standards-setters because they must be. They
require [2] to use strong crypto, because it is their asses if they don't.
They don't care, and don't need to care, if [2] understands the value of
strong crypto, as long as [2] uses it in communication with [1].

 Although [3-Joe Sixpack] may not understand or appreciate
 encryption, [3]'s support is helpful to protect [1]'s
 cryptography rights.  Furthermore once [3] has crypto, [3] will
 resist attempts to take it away (along with his six pack,
 etc.).

With this, I fully agree. The challenge is to design a system that
satisfies the security requirements for [1]'s threat model and the
usability requirements for [3]'s attention span. It has yet to be done.
All attempts thus far have been lucky if they only fail at one of those
two goals. Most fail at both.
