Near-Collision Attack on the Compression Function of Dynamic SHA2

Abstract

In this paper, we present a near-collision attack on the compression functions of Dynamic SHA2 for all the output sizes. For the Dynamic SHA2-224/256, the complexity is about 2 operations and for the Dynamic SHA2-384/512, the complexity is about 2. 1 Description of Dynamic SHA2 The Dynamic SHA-2 [1] is an iteration cryptographic hash function family which… (More)
