Witryna27 maj 2024 · The combined structure requires us to considering both stream and block cipher attacks. 1. Birthday attack: In a birthday attack, the attacker aims to find two groups of identical states, which have initialized with two different IVs and fixed keys. 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].
