    Reconfigurable architectures and cryptography : a robustness analysis and countermeasures against side channel attacks


  • Abstract

    This work addresses the reconfigurable architectures for cryptographic applications theme, emphasizing the robustness issue. Some mathematical background is reviewed, as well the state of art of reconfigurable architectures. Side channel attacks, specially the DPA and SPA attacks, are studied. As consequence, algorithmic, hardware and architectural countermeasures are proposed. A new parallel reconfigurable architecture is proposed to implement the Leak Resistant Arithmetic. This new architecture outperforms most of state of art circuits for modular exponentiation, but the main feature of this architecture is the robustness against DPA attacks


  • Abstract

    Ce travail constitue une étude sur la conception d’une architecture reconfigurable pour la cryptographie. Divers aspects sont étudiés, tels que les principes de base de la cryptographie, l’arithmétique modulaire, les attaques matériaux et les architectures reconfigurables. Des méthodes originales pour contrecarrer les attaques par canaux cachés, notamment la DPA, sont proposés. L’architecture proposée est efficace du point de vue de la performance et surtout est robuste contre la DPA
