Second cryptanalysis prize deadline extension

3 July 2009

In May, we announced the second prize for the best cryptanalysis on Keccak to encourage third-party analysis. As no submission has been received yet, we have decided to extend the deadline: the results must be publicly available on an URL that is sent to keccak -at- noekeon -dot- org before Monday August 31st, 2009 at 23:59 GMT+2.

The prize itself is also extended and now consists of the full travel set, including the Bialetti coffee machine, cups, spoons, a canister for sugar, some of the best Italian coffee and a case for easy carry to cryptographic conferences.

Again, we hope analyzing Keccak is a fun and interesting challenge, and we appreciate any submitted work!
