Witrynathe rst published collision nding attacks on reduced-round versions of Keccak-384 and Keccak-512, providing actual collisions for 3-round versions, and describing an attack which is 245 times faster than birthday attacks for 4-round Keccak-384. For Keccak-256, we increase the number of rounds which can be attacked to 5.

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 … 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. 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]. software to open dat file

WitrynaThis problem was mainly studied after 2002. Not being able to solve this problem is critical for cryptography as it gives a fast attack against FSB, SWIFFT and learning … WitrynaThis paper presents a generalized- birthday attack that uses a machine of size 22 B/(2i+1)for time 2 to find (m 1,...,m k) such that f 1(m 1) + ··· + f k(m k) mod 2 B= 0. The exponents 2/(2i + 1) and 1/(2i + 1) are smaller than the exponents for Wagner’s original generalized-birthday attack.
