Sécurité cryptographique par la conception spécifique de circuits intégrés.

Abstract : Differential Power Analysis (DPA) is a powerful side channel attack aiming at recovering secret information embedded into integrated circuits by monitoring overall power consumption. For instance, cipher keys can be recovered during cryptographic computations. The purpose of this these is to propose an efficient countermeasure based on the design of intrinsic DPA-proof gates with logic state-independent electrical consumption. With such a gates, designing a DPA-proof integrated circuit is theoretically possible. The proposed counter-measure is examined under precise microelectronics based considerations to explain the microelectronic sources of DPA. The proposed solution focuses on Complementary Metal Oxide Silicon (CMOS) integrated circuits implementing cryptographic algorithms such as the Advanced Encryption Standard (AES).
