Analyzing Masked Ciphers Against Transition and Coupling Effects

Siemen Dhooghe

Abstract

This paper discusses how to analyze the probing security of masked symmetric primitives against the leakage effects from CHES 2018; glitches, transitions, and coupling effects. This is illustrated on several architectures of ciphers like PRESENT, AES, and ASCON where we transform glitch-extended probing secure maskings into transition and/or coupling secure ones. The analysis uses linear cryptanalytic methods and the diffusion layers of the cipher to efficiently protect against the advanced leakage effects.
