Abstract

This chapter summarizes the security properties of BLAKE, as well as the attacks found on reduced or modified versions. First, we present a bottom-up analysis of the properties of BLAKE’s building blocks, necessary for the understanding of more advanced results. Then actual attacks on reduced versions of the hash function or of its components (compression function, permutation) are described. The focus is on differential cryptanalysis, the tool of choice for analyzing—and ultimately breaking—hash functions.
