$10,000 Twofish Cryptanalysis Contest

To stimulate research into Twofish, the designers put their money where their math is. They offered $10,000 in prize money for the best attack on Twofish during the first round of the AES evaluation.

Congratulations to Fauzan Mirza and Sean Murphy, who won the contest for their paper An Observation on the Key Schedule of Twofish [PDF].
