Dynamic Random Probing Expansion with Quasi Linear Asymptotic Complexity
Sonia Belaïd, Matthieu Rivain, Abdul Rahman Taleb, and Damien Vergnaud
Abstract
The masking countermeasure is widely used to protect cryptographic implementations against side-channel attacks. While many masking schemes are shown to be secure in the widely deployed probing model, the latter raised a number of concerns regarding its relevance in practice. Offering the adversary the knowledge of a fixed number of intermediate variables, it does not capture the so-called horizontal attacks which exploit the repeated manipulation of sensitive variables. Therefore, recent works have focused on the random probing model in which each computed variable leaks with some given probability
