On the Optimization of Side-Channel Attacks by Advanced Stochastic Methods

Abstract. A number of papers on side-channel attacks have been published where the side-channel information was not exploited in an optimal manner, which reduced their efficiency. A good understanding of the source and the true risk potential of an attack is necessary to rate the effectiveness of possible countermeasures. This paper explains a general approach to optimize the efficiency of side-channel attacks by advanced stochastic methods. The approach and its benefits are illustrated by examples.
