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
org before Tuesday November 30, 2010 at 23:59 GMT+1.
