We experiment relative merits of information-theoretic metrics such as guessing entropy, conditional Shannon or Renyi entropies vs. success probability, in the problem of guessing a cryptographic key form a leakage in some practical cryptosystems, with Hamming weight leakage model in additive (Gaussian) measurement noise.
This is ongoing work with Sylvain Guilley (Télécom Paris, Secure-IC) and Olivier Rioul (Télécom Paris).
