The starting point for collision attacks on practical hash functions is a local collision. In this paper, we make a systematic study of local collisions for the SHA-2 family. The p...

We introduce a new concept in splice-and-cut attacks on hash functions, which bridges the gap between preimage attacks and a powerful method of differential cryptanalysis. The ne...

Hash functions are an important cryptographic primitive. They are used to obtain a fixed-size fingerprint, or hash value, of an arbitrary long message. We focus particularly on ...
