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.
