Hamsi is one of the 14 second-stage candidates in NIST’s SHA-3 competition. The only previous attack on this hash function was a very marginal attack on its 256-bit version publi...
Hardware implementations of cryptographic algorithms are still vulnerable to side-channel attacks. Side-channel attacks that are based on multiple measurements of the same operatio...
Abstract. In this paper we combine a recent rotational cryptanalysis with the rebound attack, which results in the best cryptanalysis of Skein, a candidate for the SHA-3 competitio...

Ding et al [DNRS97] propose a stream generator based on several layers. We present several attacks. First, we observe that the non-surjectivity of a linear combination step allows ...

Hash functions are an important building block in almost all security applications. In the past few years, there have been major advances in the cryptanalysis of hash functions, es...
