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…
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…
Formally Proved Security of Assembly Code Against Power Analysis: A Case Study on Balanced Logic
Pablo Rauzy, Sylvain Guilley, Zakaria Najm
In his keynote speech at CHES 2004, Kocher advocated that side-channel attacks were an illustration that formal cryptography was not as secure as it was believed because some assum…
Countermeasures Against High-Order Fault-Injection Attacks on CRT-RSA
Pablo Rauzy, Sylvain Guilley
In this paper we study the existing CRT-RSA countermeasures against fault-injection at-tacks. In an attempt to classify them we get to achieve deep understanding of how they work.…
