Grøstl Distinguishing Attack: A New Rebound Attack of an AES-like Permutation

We consider highly structured truncated differential paths to mount a new rebound attack on Grøstl-512, a hash functions based on two AES-like permutations, P1024 and Q1024, with non-square input and output registers. We explain how such differential paths can be computed using a Mixed-Integer Linea...
