La soci\u00e9t\u00e9 Google a annonc\u00e9 le d\u00e9but de l'utilisation de puces bas\u00e9es sur la plateforme ouverte OpenTitan dans les appareils Chromebook. Les Chromebook sont devenus les premiers dispositifs commercialement disponibles \u00e9quip\u00e9s d'OpenTitan. Par la suite, cette ann\u00e9e, Google pr\u00e9voit de commencer l'impl\u00e9mentation de syst\u00e8mes serveurs avec OpenTitan dans ses data centers. La production de masse des puces est organis\u00e9e par la soci\u00e9t\u00e9 Nuvoton. Il a \u00e9galement \u00e9t\u00e9 mentionn\u00e9 le d\u00e9but du travail sur une deuxi\u00e8me version de la puce, qui permettra d'utiliser des algorithmes de cryptographie post-quantique ML-DSA et ML-KEM pour un d\u00e9marrage s\u00e9curis\u00e9 et une attestation, mettant en \u0153uvre des m\u00e9thodes cryptographiques bas\u00e9es sur la r\u00e9solution de probl\u00e8mes de th\u00e9orie des r\u00e9seaux.

Le projet OpenTitan fournit une plateforme pour la cr\u00e9ation de composants mat\u00e9riels dignes de confiance (RoT, Root of Trust), utilis\u00e9s l\u00e0 o\u00f9 il est n\u00e9cessaire de garantir l'int\u00e9grit\u00e9 des \u00e9l\u00e9ments mat\u00e9riels et logiciels du syst\u00e8me. OpenTitan a \u00e9t\u00e9 fond\u00e9 par Google en 2018, mais a \u00e9t\u00e9 transf\u00e9r\u00e9 en 2019 \u00e0 l'organisation \u00e0 but non lucratif lowRISC, apr\u00e8s quoi des entreprises telles que Western Digital, Seagate, Nuvoton Technology, Winbond, Rivos, zeroRISC et G+D Mobile Security ont rejoint son d\u00e9veloppement. Le code et les sp\u00e9cifications des composants mat\u00e9riels li\u00e9s au projet sont publi\u00e9s sous la licence Apache 2.0. Les solutions appliqu\u00e9es dans OpenTitan reposent sur des technologies d\u00e9j\u00e0 utilis\u00e9es dans les jetons USB cryptographiques Google Titan et les puces TPM pour assurer un d\u00e9marrage v\u00e9rifi\u00e9. serveurs<\/a> l'infrastructure de Google, ainsi que sur des appareils Chromebook et Pixel. <\/p>\n

Contrairement aux impl\u00e9mentations existantes du Root of Trust, OpenTitan \u00e9volue selon le concept de \u00ab s\u00e9curit\u00e9 par la transparence \u00bb, ce qui implique la disponibilit\u00e9 du code et des sch\u00e9mas, ainsi qu'un processus de d\u00e9veloppement enti\u00e8rement ouvert, ind\u00e9pendant des fournisseurs et des fabricants de puces sp\u00e9cifiques. OpenTitan est devenue la premi\u00e8re impl\u00e9mentation ouverte du Root of Trust commercialis\u00e9e, avec un support pour un m\u00e9canisme de d\u00e9marrage s\u00e9curis\u00e9 post-quantique bas\u00e9 sur l'utilisation de l'algorithme de signature num\u00e9rique SLH-DSA (Sphincs+), r\u00e9sistant \u00e0 la cryptanalyse par des ordinateurs quantiques. <\/p>\n

Les puces bas\u00e9es sur OpenTitan peuvent \u00eatre utilis\u00e9es dans les cartes m\u00e8res de serveurs, les cartes r\u00e9seau, les appareils grand public, les routeurs et les dispositifs IoT pour la v\u00e9rification des firmwares et des composants charg\u00e9s (protection contre la modification des parties critiques du syst\u00e8me), pour la g\u00e9n\u00e9ration d'identifiants syst\u00e8me cryptographiquement uniques (protection contre le remplacement de mat\u00e9riel), pour fournir des services li\u00e9s \u00e0 la s\u00e9curit\u00e9, pour prot\u00e9ger les cl\u00e9s cryptographiques (isolation des cl\u00e9s en cas d'acc\u00e8s physique non autoris\u00e9 au mat\u00e9riel) et pour tenir un journal d'audit isol\u00e9, qui ne peut pas \u00eatre modifi\u00e9 ou effac\u00e9. <\/p>\n

OpenTitan inclut des blocs logiques demand\u00e9s dans les puces RoT, tels qu'un microprocesseur ouvert bas\u00e9 sur l'architecture RISC-V (RV32IMCB Ibex), des coprocesseurs cryptographiques, un g\u00e9n\u00e9rateur de nombres al\u00e9atoires mat\u00e9riel, un gestionnaire de cl\u00e9s prenant en charge DICE, un m\u00e9canisme de stockage s\u00e9curis\u00e9 des donn\u00e9es en m\u00e9moire permanente et en RAM, des technologies de protection, des blocs d'entr\u00e9e\/sortie et des composants de d\u00e9marrage s\u00e9curis\u00e9. L'appareil fournit \u00e9galement des blocs avec la mise en \u0153uvre d'algorithmes de chiffrement standard tels que AES et HMAC-SHA256, et un acc\u00e9l\u00e9rateur d'op\u00e9rations math\u00e9matiques utilis\u00e9es dans les algorithmes pour les signatures num\u00e9riques bas\u00e9es sur des cl\u00e9s publiques. <\/p>\n
