In February, we announced the Hex-Hot-Ticks prize for the most interesting implementation of Keccak on exotic platforms and one month later the fourth prize for the best cryptanalysis to encourage third-party analysis of Keccak. The deadline for both prizes was set to June 30, 2010.

However, as we planned to announce the winners during the rump session of the SHA-3 workshop in Santa Barbara on August 23-24, we have decided to extend the deadline to midnight August 20. This will allow the submission of results obtained during the summer, including the SAC workshop and the CHES and CRYPTO conferences.

The results must be publicly available on an URL that is sent to keccak -at- noekeon -dot- org before Friday August 20, 2010 at 23:59 PDT (GMT-7).
