Title:
Near-Collision Attack on the Compression Function of Dynamic SHA2
Authors: Hongbo Yu, Xiaoyun Wang
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^{45} operations and for the Dynamic SHA2-384/512, the complexity is about 2^{75}.
