Side-channel analysis is an important issue for the security of embedded cryptographic
devices, and masking is one of the most investigated solutions to mitigate such attacks. In …

The design and analysis of lightweight block ciphers has been a very active research area
over the last couple of years, with many innovative proposals trying to optimize different …

Side-Channel Attacks (SCA) are considered a serious threat against embedded
cryptography. Therefore security critical chips must be tested for SCA resistance before …

Side-channel analysis (SCA) is a serious threat to embedded cryptography. Any SCA has
two important components: leakage modeling and distinguisher. Although distinguisher has …

Simulation is a very powerful tool for hardware designers. It generally allows the preliminary
evaluation of a chip's performance before its final tape out. As security against side-channel …

The design and the security verification of side-channel resistant cryptographic hardware
often represent an iterative process. This process essentially consists of a detection phase …

This thesis considers encrypted computation where the user specifies encrypted inputs to an
untrusted batch program controlled by an untrusted server. In batch computation, all data …

Profiling power attacks like Template attack and Stochastic attack optimize their performance
by jointly evaluating the leakages of multiple sample points. However, such multivariate …

The security of cryptographic algorithms can be considered in two contexts. On the one
hand, these algorithms can be proven secure mathematically. On the other hand, physical …

Cette thèse se situe dans la cryptanalyse physique des algorithmes de chiffrement par
blocs. Un algorithme cryptographique est conçu pour être mathématiquement robuste …
