Webb18 juli 2024 · Random masking is a widely used countermeasure for removing the statistical dependence between secret data and side-channel information. Although there are techniques for verifying whether a piece of software code is perfectly masked, they are limited in accuracy and scalability.

WebbAbstract. Secure elements, such as smartcards or trusted platform modules (TPMs), must be protected against implementation-level attacks. Those include side-channel and fault injection attacks. We introduce ODSM, Orthogonal Direct Sum Masking, a new computation paradigm that achieves protection against those two kinds of attacks.
