Extension of the fourth cryptanalysis and Hex-Hot-Ticks prizes

8 September 2010

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 fourth cryptanalysis prize consisted of a box of 600g of the finest Belgian pralines. We increase this now to 1200g. To be gentle on your liver, please consider submitting as a team or sharing the pralines with your relatives. :-)

The deadline of both prizes is extended to November 30, 2010. The results must be publicly available on an URL that is sent to keccak -at- noekeon -dot- org before Tuesday November 30, 2010 at 23:59 GMT+1.
