Biclique Attack of the Full ARIA-256

Shao-zhen Chen Tian-min Xu

Abstract

In this paper, combining the biclique cryptanalysis with the MITM attack, we present the first key recovery method for the full ARIA-256 faster than brute-force. The attack requires $2^{80}$ chosen plaintexts, and the time complexity is about $2^{255.2}$ full-round ARIA encryptions in the processing phase.
