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.

Improved Preimage Attacks on AES-like Hash Functions: Applications to Whirlpool and Grøstl ... how do you calculate the acid test ratioThe 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]. pho noodles recipe chickenWitrynaThis 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. pho noodles in bonifay flWitryna1 kwi 2011 · Birthday Attac ks can be improved by a factor of r when applied to a structured matrix of size r × n .
