La soci\u00e9t\u00e9 Google pr\u00e9sent\u00e9e<\/a><\/noindex> nouveau projet ouvert OpenTitan<\/a><\/noindex>, qui est une plateforme pour la cr\u00e9ation de composants mat\u00e9riels de confiance (RoT, Root of Trust). OpenTitan repose sur des technologies d\u00e9j\u00e0 utilis\u00e9es dans les tokens USB cryptographiques. Google Titan<\/a><\/noindex> et puces TPM<\/a><\/noindex> pour assurer un d\u00e9marrage v\u00e9rifi\u00e9, install\u00e9es sur des serveurs dans l'infrastructure de Google, ainsi que sur des appareils Chromebook et Pixel. Le code et les sp\u00e9cifications mat\u00e9riels associ\u00e9s au projet publi\u00e9s<\/a><\/noindex> sont disponibles sur GitHub sous licence Apache 2.0.<\/p>\n

Contrairement aux r\u00e9alisations existantes du Root of Trust, le nouveau projet se d\u00e9veloppe selon le concept de \u00ab s\u00e9curit\u00e9 par transparence \u00bb, impliquant un processus de d\u00e9veloppement enti\u00e8rement ouvert et l'accessibilit\u00e9 du code et des sch\u00e9mas. OpenTitan peut \u00eatre utilis\u00e9 comme une structure pr\u00eate, \u00e9prouv\u00e9e et fiable, permettant d'accro\u00eetre la confiance dans les solutions cr\u00e9\u00e9es et de r\u00e9duire les co\u00fbts lors du d\u00e9veloppement de puces sp\u00e9cialis\u00e9es pour assurer la s\u00e9curit\u00e9. OpenTitan \u00e9voluera sur une plateforme ind\u00e9pendante en tant que projet collaboratif, sans \u00eatre li\u00e9 \u00e0 des fournisseurs et fabricants de puces sp\u00e9cifiques. <\/p>\n

Le d\u00e9veloppement d'OpenTitan sera supervis\u00e9 par une organisation \u00e0 but non lucratif lowRISC<\/a><\/noindex>, qui d\u00e9veloppe un microprocesseur libre bas\u00e9 sur l'architecture RISC-V. Des entreprises comme G+D Mobile Security, Nuvoton Technology et Western Digital, ainsi que l'\u00c9cole polytechnique f\u00e9d\u00e9rale de Zurich et l'Universit\u00e9 de Cambridge, dont les chercheurs d\u00e9veloppent une architecture de processeur s\u00e9curis\u00e9e, se sont d\u00e9j\u00e0 jointes \u00e0 la collaboration sur OpenTitan. CHERI<\/a><\/noindex> (Capability Hardware Enhanced RISC Instructions) et r\u00e9cemment par les militaires russes. Pour d\u00e9truire les donn\u00e9es avec le support, il suffit d'appuyer sur un bouton. En principe, un syst\u00e8me artisanal similaire peut \u00eatre fait soi-m\u00eame ou achet\u00e9 en ligne \u2014 il y en a plusieurs.<\/a><\/noindex> un don de 190 millions d'euros pour l'adaptation des technologies associ\u00e9es pour les processeurs ARM et la cr\u00e9ation d'un prototype de nouvelle plateforme mat\u00e9rielle Morello.<\/p>\n

Le projet OpenTitan couvre le d\u00e9veloppement de divers composants logiques, demand\u00e9s dans les puces RoT, y compris un microprocesseur ouvert lowRISC Ibex<\/a><\/noindex> bas\u00e9e sur l'architecture RISC-V, des coprocesseurs cryptographiques, un g\u00e9n\u00e9rateur mat\u00e9riel de nombres al\u00e9atoires, une hi\u00e9rarchie de stockage des cl\u00e9s et des donn\u00e9es en m\u00e9moire permanente et volatile, des m\u00e9canismes de protection, des unit\u00e9s d'entr\u00e9e\/sortie, des m\u00e9thodes de d\u00e9marrage s\u00e9curis\u00e9, etc. OpenTitan peut \u00eatre utilis\u00e9 dans des contextes n\u00e9cessitant de garantir l'int\u00e9grit\u00e9 des composants mat\u00e9riels et logiciels du syst\u00e8me, en s'assurant que les composants syst\u00e8me critiques n'ont pas \u00e9t\u00e9 remplac\u00e9s et reposent sur un code v\u00e9rifi\u00e9 et autoris\u00e9 par le fabricant. <\/p>\n

Les puces bas\u00e9es sur OpenTitan peuvent \u00eatre utilis\u00e9es dans
\nles cartes m\u00e8res serveur, les cartes r\u00e9seau, les appareils grand public, les routeurs, les dispositifs Internet des objets pour v\u00e9rifier les firmwares (d\u00e9tection des modifications de firmware par des logiciels malveillants), fournir un identifiant unique cryptographique pour le syst\u00e8me (protection contre la substitution des \u00e9quipements), s\u00e9curiser les cl\u00e9s cryptographiques (isolement des cl\u00e9s en cas d'acc\u00e8s physique non autoris\u00e9 au mat\u00e9riel), fournir des services li\u00e9s \u00e0 la s\u00e9curit\u00e9 et maintenir un journal d'audit isol\u00e9, qui ne peut \u00eatre modifi\u00e9 ou effac\u00e9.<\/p>\n
