Improved generalized birthday attack
WitrynaOur techniques start to improve upon existing protocols when there are around n=10parties with h=4honest parties, and as these increase we obtain up to a 13 times reduction (for n=400,h=120) in communication complexity for our GMW variant, compared with the best-known GMW-based protocol modified to use the same … WitrynaImplementing Wagner's generalized birthday attack against the SHA-3 round-1 candidate FSB.
