Welcome to the resource topic for 2009/106

Title:
A Collision Attack on AURORA-512

Authors: Yu Sasaki

Abstract:

In this note, we present a collision attack on AURORA-512, which is one of the candidates for SHA-3. The attack complexity is approximately 2^{236} AURORA-512 operations, which is less than the birthday bound of AURORA-512, namely, 2^{256}. Our attack exploits some weakness in the mode of operation.
