ePrint Report: Improved Boomerang Attacks on 6-Round AES

Augustin Bariant, Orr Dunkelman, Nathan Keller, Gaëtan Leurent, Victor Mollimard

The boomerang attack is a cryptanalytic technique which allows combining two short high-probability differentials into a distinguisher for a large number of rounds. Since its introduction by Wagner in 1999, it has been applied to many ciphers. One of the best-studied targets is a 6-round variant of AES, on which the boomerang attack is outperformed only by the dedicated Square attack. Recently, …
