ePrint Report: Consolidated Linear Masking (CLM): Generalized Randomized Isomorphic Representations, Powerful Degrees of Freedom and Low(er)-cost

Itamar Levi, Osnat Keren

Masking is a widely adopted countermeasure against side-channel analysis (SCA) that protects cryptographic implementations from information leakage. However, current masking schemes often incur significant overhead in terms of electronic cost. RAMBAM, a recently proposed masking technique that fits elegantly with the AES algorithm, offers ultra-low latency/area by utilizing redundant representations of finite field elements. This paper presents a comprehensive generalization …
