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…
Asymptotically Optimal Massey-Like Inequality on Guessing Entropy With Application to Side-Channel Attack Evaluations
Andrei Tănăsescu, Marios O. Choudary, Olivier Rioul +1
A Massey-like inequality is any useful lower bound on guessing entropy in terms of the computationally scalable Shannon entropy. The asymptotically optimal Massey-like inequality i…
Designs in finite metric spaces: a probabilistic approach
Minjia Shi, Olivier Rioul, Patrick Solé
A finite metric space is called here distance degree regular if its distance degree sequence is the same for every vertex. A notion of designs in such spaces is introduced that gen…
Cumulant Expansion of Mutual Information for Quantifying Leakage of a Protected Secret
Olivier Rioul, Wei Cheng, Sylvain Guilley
The information leakage of a cryptographic implementation with a given degree of protection is evaluated in a typical situation when the signal-to-noise ratio is small. This is sol…
Variations on a Theme by Massey
Olivier Rioul
In 1994, Jim Massey proposed the guessing entropy as a measure of the difficulty that an attacker has to guess a secret used in a cryptographic system, and established a well-known…
