Title (EN) DEVICE WITH MULTIPLE ROOTS OF TRUST
(FR) DISPOSITIF AYANT DE MULTIPLES RACINES DE CONFIANCE
Abstract:
(EN) A container from a first root of trust associated with a first root entity may be received. The container may correspond to a mapping of a resource of an integrated circuit that is associated with the first root entity. The container may be verified based on a key that corresponds to the first root of trust and that is stored in the integrated circuit at manufacturing of the integrated circuit. An identification may be made that an assignment of the resource from the container corresponds to assigning the resource from the first root of trust to a new root of trust. A new key corresponding to the new root of trust may be generated. Information corresponding to the new key may be stored into a memory of the integrated circuit. Furthermore, the new key may be used to delegate the resource to a subsequent container.
(FR) Selon l’invention, un contenant provenant d’une première racine de confiance associée à une première entité de racine peut être reçu. Le contenant peut correspondre à un mappage d’une ressource d’un circuit intégré qui est associé à la première entité de racine. Le contenant peut être vérifié sur la base d’une clé qui correspond à la première racine de confiance et qui est stockée dans le circuit intégré lors de la fabrication du circuit intégré. Une identification peut être réalisée, selon laquelle une affectation de la ressource provenant du contenant correspond à l’affectation de la ressource provenant de la première racine de confiance à une nouvelle racine de confiance. Une nouvelle clé correspondant à la nouvelle racine de confiance peut être générée. Des informations correspondant à la nouvelle clé peuvent être stockées dans une mémoire du circuit intégré. En outre, la nouvelle clé peut être utilisée pour déléguer la ressource à un contenant suivant.
