- Abstract
- (en) This thesis deals with side channel attacks against hardware implementations of cryp- tographic algorithms. Studies conducted in this document are therefore in place where an adversary has access to noisy observations of intermediate results of a cryptographic computation. In this context, many attacks are dedicated with their countermeasures, but their relevance and their implementation are still unclear. This thesis initially focuses on the relevance of existing attacks and potential links between them. A formal classification is proposed as well as selection criteria. Based on this study, a generic efficient attack is described and analysed in depth. In a second step, the implementation of common countermeasures is studied, leading to the creation of an application scheme mixing them to achieve a better efficiency / security trade off.
