Maximal Leakage of Masked Implementations Using Mrs. Gerber's Lemma for Min-Entropy
Julien Béguinot, Yi Liu, Olivier Rioul +2
A common countermeasure against side-channel attacks on secret key cryptographic implementations is th-order masking, which splits each sensitive variable into random shar…

On Conditional -Information and its Application to Side-Channel Analysis
Yi Liu, Wei Cheng, Sylvain Guilley +1
A conditional version of Sibson's -information is defined using a simple closed-form "log-expectation" expression, which satisfies important properties such as consistency, unif…

Attacking Masked Cryptographic Implementations: Information-Theoretic Bounds
Wei Cheng, Yi Liu, Sylvain Guilley +1
Measuring the information leakage is critical for evaluating the practical security of cryptographic devices against side-channel analysis. Information-theoretic measures can be us…
