Congratulations to the winners of the second Keccak cryptanalysis prize

9 September 2009

We are happy to announce that Jean-Philippe Aumasson and Willi Meier are the winners of the second Keccak cryptanalysis prize for their note entitled Zero-sum distinguishers for reduced Keccak-f and for the core functions of Luffa and Hamsi. The awarded Bialetti coffee machine and its full travel set were handed over to Jean-Philippe yesterday at the rump session of CHES 2009 in Lausanne. Congratulations to them!

We will soon announce a new prize with a new deadline.
