ePrint Report: Analyzing the Leakage Resistance of the NIST's Lightweight Crypto Competition's Finalists

Corentin Verhamme, Gaëtan Cassiers, François-Xavier Standaert

We investigate the security of the NIST Lightweight Crypto Competition’s Finalists against side-channel attacks. We start with a mode-level analysis that allows us to put forward three candidates (As- con, ISAP and Romulus-T) that stand out for their leakage properties and do not require a uniform protection of all their computations thanks to (expensive) implementation-level countermeasures. We then implement these finalists …
