Le niveau de sécurité d'un système de gestion des droits numériques (DRM) de télévision sur protocole Internet (IPTV) repose en fin de compte sur la protection des clés secrètes. Les dispositifs bien connus pour la protection des clés comprennent les cartes à puce et les SRAM de batterie de secours (BB-SRAM) ; cependant, ces appareils pourraient être vulnérables à diverses attaques physiques. Dans cet article, nous proposons une conception sécurisée et rentable d'un système cryptographique sur puce (SoC) qui intègre le BB-SRAM avec une technique de conception basée sur les cellules. Le SoC proposé offre une protection robuste contre les attaques physiques et satisfait aux exigences de haut débit et de prix bas des décodeurs IPTV. Nos résultats d'implémentation montrent que le taux de cryptage maximum du SoC est de 633 Mb/s. Afin de vérifier les capacités de rétention des données, nous avons réalisé un prototype de puce utilisant la technologie des cellules standard de 0.18 µm. Les résultats expérimentaux montrent que la BB-SRAM intégrée peut conserver les données de manière fiable avec un courant de fuite de 1.4 µA.

Abstract: The security level of an internet protocol television (IPTV) digital right management (DRM) system ultimately relies on protection of secret keys. Well known devices for the key protection include smartcards and battery backup SRAMs (BB-SRAMs); however, these devices could be vulnerable to various physical attacks. In this paper, we propose a secure and cost-effective design of a cryptographic system on chip (SoC) that integrates the BB-SRAM with a cell-based design technique. The proposed SoC provides robust safeguard against the physical attacks, and satisfies high-speed and low-price requirements of IPTV set-top boxes. Our implementation results show that the maximum encryption rate of the SoC is 633 Mb/s. In order to verify the data retention capabilities, we made a prototype chip using 0.18 µm standard cell technology. The experimental results show that the integrated BB-SRAM can reliably retain data with a 1.4 µA leakage current.
