sha256 attack
Abstract. In this work, we study the application of higher-order dif- ferential attacks on hash functions. We show a second-order differential attack on the SHA-256 ... ,collisions for SHA-256, and show how to turn them into collisions. We present a collision attack on 28 steps of the hash function with practical complexity.
