Improved generalized birthday attack

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. All these results … 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 …

Implementing Wagner

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].
