Title:
New Impossible Differential Cryptanalysis of ARIA
Authors: Ruilin Li, Bing Sun, Peng Zhang, Chao Li
Abstract:This paper studies the security of ARIA against impossible differential cryptanalysis. Firstly an algorithm is given to find many new 4-round impossible differentials of ARIA. Followed by such impossible differentials, we improve the previous impossible differential attack on 5/6-round ARIA. We also point out that the existence of such impossible differentials are due to the bad properties of the binary matrix employed in the diffusion layer.
