Résumé
Nowadays, digital systems are becoming the main information support. This evolution implies a growing interest for the domain of cryptology regarding the conception of these systems. The hardware/software implementation has become one of the main weaknesses of security applications and hardware attacks, or "side channel attacks", such as DPA (Differential Power Analysis) and CPA (Current Power Analysis), have become standard. They are now identified as the most dangerous attacks, i.e. they allow ciphering algorithm keys discovery, like those used in smartcards, with minor cost and effort. In this context, the missions of this platform, supported by the "Région Languedoc Roussillon" and the "Université Montpellier 2", are to analyze the security potentialities of hardware platforms and embedded systems. This platform involves disciplinary competencies like Mathematics (I3M laboratory, Montpellier), Informatics and Microelectronics (LIRMM laboratory, Montpellier) and Electronics (IES laboratory, Montpellier). Our equipment allows us to perform process characterization as well. This platform is clearly part of a scientific and technical transverse approach in the "Université Montpellier 2" and "Pôle MIPS" (Mathematics, Informatics, Physics and System) scene.
