Abstract

Abstract : In this study, combining the biclique cryptanalysis with the meet‐in‐the‐middle (MITM) attack, the authors 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.
