A birthday attack belongs to the family of brute force attacks and is based on the probability theorem. It is a cryptographic attack and its …
WitrynaGeneralized Birthday Arracks on Unbalanced Feistel Networks Unbalanced Feistel networks Fk which are used to construct invertible pseudo-random permutations … 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].
