Improved Related-Key Differential Attacks against AES-256
Anubhab Baksi, Ajay Das, Smita Das, Patrick Derbez et autres
In this paper, we revisit the differential meet-in-the-middle attack and classical differential attack on AES-256 under the related-key setting, as introduced in Boura et al.'s ToSC 2023 and Song et al.'s Asiacrypt 2024 works. We propose new attacks against 13-round AES-256, all …
