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 solved by expanding Kullback-Leibler divergence, entropy, and mutual information in terms of moments/cumulants.
