Protecting white-box aes with dual ciphers

Webb11 nov. 2024 · The study of white-box security was revamped by recent advances involving grey box attacks. Since then, many authors have struggled to protect implementations against such new attacks. New designs as well as new security notions appeared, and white-box research in general seems to have greatly benefited from such advances. WebbIn this paper, we present an improved white-box implementation of AES. We use dual ciphers to modify the state and key representations in each round as well as two of the four classical AES operations, SubBytes and MixColumns. We show that, with 61200 possible dual ciphers the complexity of Billet et al. attack is raised to 291.
