Abstract:Abstract. Distinguishers play an important role in Side Channel Analysis (SCA), where real world leakage information is compared against hypothetical predictions in order to guess at the underlying secret key. However, the direct relationship between leakages and predictions can be disrupted by the mathematical combining of d random values with each sensitive intermediate value of the cryptographic algorithm (a so-called "d-th order masking scheme"). In the case of software implementations, as long as the mask… Show more
