"Unbreakable Crypto" announcement??
Does anyone with access to the Financial Times know what the hell this snippet is talking about?? -=fade=- ENCRYPTION BREAKTHROUGH ANNOUNCED TODAY August 24, 1998 According to the Financial Times a new "unbreakable" encryption technology, called the "Cramer-Shoup cryptosystem," will be annouced today by mathematicians from the International Federal Institute of Technology which supposedly will thwart even the most aggressive Internet hackers. They claim to have created the first "unbreakable protection" which would reportedly be a breakthrough that could ensure the security of electronic commerce. The Financial Times said, "The breakthrough comes amid growing anxiety about the vulnerability of Internet transactions since the discovery by researchers earlier this year of a new way to break through even the strongest encryption systems."

Well this marketing hype just reeks of snake-oil.
It may be rash to condemn or dismiss a cryptographic proposal just because corporate PR is unable to coherently explain the work. Cramer and Shoup are serious players, and they are presenting a paper on their work at Crypto98 today. The technical paper can be viewed at: <http://www.zurich.ibm.com/Technology/Security/publications/1998/CS.pdf> For more uninformative PR, see: <http://biz.yahoo.com/bw/980824/ibm_resear_1.html> IBM (Shoup's employer) offers a PR contact: Mike Ross, at IBM Research, e-mail: mikeross@almaden.ibm.com [Tel: 408/927-1283] Suerte, _Vin ----- Vin McLellan + The Privacy Guild + <vin@shore.net> 53 Nichols St., Chelsea, MA 02150 USA <617> 884-5548 -- <@><@> --

ENCRYPTION BREAKTHROUGH ANNOUNCED TODAY August 24, 1998
According to the Financial Times a new "unbreakable" encryption technology, called the "Cramer-Shoup cryptosystem," will be annouced today by mathematicians from the International Federal Institute of Technology which supposedly will thwart even the most aggressive Internet hackers. They claim to have created the first "unbreakable protection" which would reportedly be a breakthrough that could ensure the security of electronic commerce. The Financial Times said, "The breakthrough comes amid growing anxiety about the vulnerability of Internet transactions since the discovery by researchers earlier this year of a new way to break through even the strongest encryption systems."
Who would have guessed that a journalist would so grievously misrepresent the claims of a soberly presented scholarly report? The title of the technical paper is: "A Practical Public Key Cryptosystem Provably Secure against Adaptive Chosen Ciphertext Attack". The only new claim is security against a chosen ciphertext attack, not "unbreakable". The specific internet angle is that an attacker might have access to a "decryption oracle" due to the nature of high volume anonymous transactions. If one could slip through a few million adaptively chosen ciphertexts, current systems could leak enough information to compromise themselves. The reported results are for a new proposed system that is not vulnerable to this sort of attack.

It's not snake oil (yet?), but the word unbreakable is lame. check out a preliminary paper on it... http://www.cs.wisc.edu/~shoup/papers/ Title A practical public key cryptosystem provably secure against adaptive chosen ciphertext attack Fade wrote:

Cramer & Shoup presented a paper this AM with some provable properties; ie, if decisional DH is hard, then their system is hard as well.
