Title:
Biclique Attack of the Full ARIA-256

Authors: 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.
