Abstract: This note describes an SPA-based side channel attack against a CRT implementation of an RSA function. In contrast with Novak?s attack [8], it concentrates on the initial modular reduction. With the help of lattice reduction it applies even to implementations which use a common randomising technique to ensure resistance against certain side channel attacks.
