International Association for Cryptologic Research

Ph.D. Database

The aim of the IACR Ph.D. database is twofold. On the first hand, we want to offer an overview of Ph.D. already completed in the domain of cryptology. Where possible, this should also include a subject classification, an abstract, and access to the full text. On the second hand, it deals with Ph.D. subjects currently under investigation. This way, we provide a timely map of contemporary research in cryptology. All entries or changes need to be approved by an editor. You can contact them via phds (at)

Abstract This thesis develops an overview of the so called Side Channel Attacks (SCA). In order to counter these attacks against implementations, it is proposed solutions at three different levels : the hardware level, the mathematic level and the algorithmic level. The state of the art of SCA provided in the second chapter, underlines clearly that the side channels provide multiple attack paths to attackers. At the hardware level, the results obtained in the European project ESPASS-IS have led to the definition of new and innovative projects between the TIMA Laboratory, the LIRMM and STMicroelectronics. At the mathematical level, the definition of a Leak Resistant Arithmetic (LRA), in collaboration with the LIRMM, was the starting point of a several open research subjects. Among these, are the perspective of new arithmetics both efficient and compact taking into account a new vector of optimizations : the robustness to fault injection and the minimization of side channel leakage. At the algorithmic level, the article published at CHES'00 has been in the very first work on securization of elliptic curves implementations and is cited in many publication of the field..
