The Keccak crunchy crypto contest continues through end 2013

24 January 2013

In a previous announcement, we re-opened the Keccak Crunchy Crypto Collision and Pre-image contest until end 2012. As no new challenges were solved between March and December 2012, we decided to leave it open for another year, i.e., until end 2013.

The challenges remain the same. We suggest all interested people to subscribe to our mailing list, and solutions shall be sent to this mailing list, as detailed here, before December 31, 2013 at 23:59 GMT+1.
