ePrint Report: Algorithms for switching between block-wise and arithmetic masking

Evgeny Alekseev, Andrey Bozhko

The task of ensuring the required level of security of information systems in the adversary models with additional data obtained through side channels (a striking example of implementing threats in such a model is a differential power analysis) has become increasingly relevant in recent years. An effective protection method against side-channel attacks is masking all intermediate variables used in the algorithm with random values. At the …
