New Impossible Differential Cryptanalysis of ARIA

Ruilin Li, Bing Sun, Peng Zhang, and 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.

Note: correction for 5 round attack
