WitrynaWe generalize the birthday attack presented by Coppersmith at Crypto'8S which defrauded a Davies-Price message authentication scheme. We first study the … The new attack combines linearization and generalized birthday attacks and thus, is faster than all these attacks. Furthermore, both algorithms are slightly improved. This leads to practical attacks against the cryptosystems. The algorithm was implemented and allowed to nd a collision in FSB-48 in far less ressources than previously in [3].

Witryna1 lis 2024 · In this study, the authors present some new algorithms for the unbalanced generalised birthday problem (UGBP), which was proposed by Nikolić and Sasaki in their attacks on the generalised birthday problem (GBP). The authors’ first idea is simple, which uses some precomputing to convert UGBP into GBP. 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 …
