As long as no official publication has been finished and approved by our Government, I cannot send you details about the algorithms." "But I confirm that new methods based on Artificial Intelligence allow fast attacks on block-cipher algorithms." "I tested the procedure with DES, and I hope to get the necessary computer equipment soon, in order to apply it to AES and to develop efficient protection software against the new attacks." here is more recent "final" follow-up: ===SNIP=== Date: Fri, 25 Jan 2002 10:50:21 +0100 From: Lutz Donnerhacke <lutz@iks-jena.de> To: krypto@thur.de Subject: Final Message to all people interested in DES ----- Forwarded message from Pascal ZEIHEN <pascal.zeihen@ci.educ.lu> --- -- Good morning, I have been abroad for a week and now I find hundreds of messages about DES in my mailbox. Here is some useful information: * My approach to break block-cipher algorithms is based on AI and heuristical methods. Its first implementation works only if the plaintext verifies certain special conditions (about length, entropy, data layout). Unfortunately, such essential details are not described in newspaper articles. * A first test series took place on December 13, 2001, in the grammar high school in Diekirch, where the required computer equipment was available. The tests were successful, and the applied procedure was approved by mathematicians, computer scientists and a notary. As suggested by some people, future test series will also include foreign experts to be chosen and invited to Luxembourg by the Foundation described below. * For privacy reasons, all my research work related to the DES project will be transferred to a Foundation. After it has started its work, you will find information about it on the web. * I am a mathematician, not a hacker; I do not "crack" data for people I do not personally know. Please do not send any more copy-protected games (software protection has nothing to do with DES!!), test data, questions or suggestions to my private address. Thank you.
