Quantum cryptanalysis of hash and claw-free functions

Hash function cryptanalysis has acquired many methods, tools and tricks from other areas, mostly block ciphers. In this paper another trick from block cipher cryptanalysis, the structures, is used for speeding up the collision search. We investigate the ...

It is well-known that blockcipher-based hash functions may be attacked when adopting blockciphers having related-key differential properties. However, all forms of related-key differentials are not always effective to attack them. In this paper we ...

ESSENCE is a family of cryptographic hash functions, accepted to the first round of NIST's SHA-3 competition. This paper presents the first known attacks on ESSENCE. We present a semi-free-start collision attack on 31 out of 32 rounds of ESSENCE-512, ...
