Lorenzo Grassi, Loïc Masure, Pierrick Méaux, Thorben Moos, François-Xavier Standaert

A recent work from Eurocrypt 2023 suggests that prime-field masking has excellent potential to improve the efficiency vs. security tradeoff of masked implementations against side-channel attacks, especially in contexts where physical leakages show low noise. We pick up on the main open challenge that this seed result leads to, namely the design of an optimized prime cipher …
