Hi all! At the rump session of Crypto 2006, we started the "chasing the Rabbit" contest. Dan Bernstein was so kind as to present the slides on our behalf. The details of the contest are given below; they can also be downloaded from http://www.cryptico.com/Files/Filer/rabbit_contest.pdf.

It used a novel approach for pseudo-random output generation and provided very high performance. Now, 3 1/2 years later, Rabbit is still unbroken. Starting from August 1, 2006, Cryptico A/S starts the Rabbit contest. The purpose is to encourage further research and analysis, but also the publication of already existing results. For the most interesting paper on Rabbit cryptanalysis, Cryptico A/S offers a price of US $ 1000. In order to qualify for the competition, a paper has to meet the following conditions: - At least part of the paper deals with cryptanalysis of the Rabbit stream cipher. - Cryptanalysis may be of the full cipher, of a reduced version, or of cipher components. - The paper has been accepted for presentation at a cryptographic conference with fully reviewed proceedings (either online or printed), or for publication in an academic journal of good standing. - Cryptico A/S has been notified about the paper's existence and the conference or journal it has been accepted for. The closing date of the competition is September 30, 2007. After that date, the Cryptico jury will decide on which paper it considers to be the most interesting. We preserve the right to split the price money between several contestants, if this seems most appropriate. Closing remarks: - Employees, former employees, and advisory board members of Cryptico A/S may not participate. - The specification of the Rabbit stream cipher and the white papers on cryptanalysis are available from the Cryptico homepage, http://www.cryptico.com/. - For any questions or comments, please contact [EMAIL PROTECTED] --------------------------------------------------------------------- The Cryptography Mailing List Unsubscribe by sending "unsubscribe cryptography" to [EMAIL PROTECTED]
