A Methodology for the Characterisation of Leakages in Combinatorial Logic
2017
Glitches represent a great danger for hardware implementations of cryptographic schemes. Their intrinsic random nature makes them difficult to tackle and their occurrence threatens side-channel protections. Although countermeasures aiming at structurally solving the problem already exist, they usually require some effort to be applied or introduce non-negligible overhead in the design. Our work addresses the gap between such countermeasures and the naive implementation of schemes being vulnerable in the presence of glitches. Our contribution is twofold: (1) we expand the mathematical framework proposed by Brzozowski and Esik (FMSD 2003) by meaningfully adding the notion of information leakage, (2) thanks to which we define a formal methodology for the analysis of vulnerabilities in combinatorial circuits when glitches are taken into account.
