The authors propose a new technique called differential cluster analysis for side-channel key recovery attacks. This technique uses cluster analysis to detect internal collisions and it combines features from previously known collision attacks and differential power analysis. It captures more general leakage features and can be applied to algorithmic collisions as well as implementation specific collisions. In addition, the concept is inherently multivariate. Various applications of the approach are possible: with and without power consumption model and single as well as multi-bit leakage can be exploited.
