MAGNITUDE SQUARED COHERENCE BASED SCA

Sebastien Tiran, Amine Dehbaoui, and Philippe Maurine

Abstract

Magnitude Squared Coherence is a signal processing tool that indicates how well two time domain signals match one with the other by tracking linear dependencies in their spectral decomposition. This paper introduces different ways of using the Magnitude Squared Coherence for Side Channel Analysis. This distinguisher has several advantages over well-known distinguishers.
