Third cryptanalysis prize deadline extension

8 December 2009

In September, we announced the third 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 Saturday February 13th, 2010 at 23:59 GMT+1 (i.e., before the carnival).

In addition to the bottles of Lambic-based beer, the prize also comes with a guide about Brussels' beers to better enjoy their special taste.

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