In this approach, we base the security of hash function on some hard mathematical problem and we prove that finding collisions of the hash functions is as hard as breaking the underlying problem. This gives a somewhat stronger notion of security than just relying on complex mixing of bits as in the classical approach. A cryptographic hash function has provable security against collision attacks if finding collision… WebbIndeed, constructing an eﬃcient and provable hash function seems a big challenge nowadays. Cayley hashes In this paper, we examine three satisfactory solutions to this problem: the ZT hash function, which was designed in the past by Z´emor and Tillich [22], the LPS hash function, whose eﬃciency we greatly enhance, and the Morgenstern hash
