Conception d'un système d'alimentation intégré dédié à la sécurisation des cartes à puce

Abstract : The power supply current of a smart card exhibits significant correlations with the data processed by its microcontroller. Power analysis attacks exploit these correlations to determine the secret keys of the embedded cryptosystems. This study deals with the design of an on-chip power supply system intended to protect smart card microcontrollers against power analysis attacks. The proposed system allows the microcontroller internal supply voltage to be regulated from the external supply voltage provided by the reader, while uncorrelating the external supply current from internal supply current. Its area and its efficiency respect the smart card constraints. Moreover, its architecture includes a new random clock generator based on, among other things, a double-scroll-like chaotic attractor. The system has been simulated with Eldo using the MM9 model and the parameters of a standard STMicroelectronics 0.18 µm CMOS process; the simulation results show its efficiency. Furthermore, the chaotic oscillator has been fabricated using the AMS 2P/4M 0.35 µm CMOS process; experimental measurements confirm the theoretical results.
