Patent

CA 2743958

An asset management system is provided, which includes a hardware module operating as an asset control core. The asset control core generally includes a small hardware core embedded in a target system on chip that establishes a hardware-based point of trust on the silicon die. The asset control core can be used as a root of trust on a consumer device by having features that make it difficult to tamper with. The asset control core is able to generate a unique identifier for one device and participate in the tracking and provisioning of the device through a secure communication channel with an appliance. The appliance generally includes a secure module that caches and distributes provisioning data to one of many agents that connect to the asset control core, e.g. on a manufacturing line or in an after-market programming session.

L'invention concerne un système de gestion d'actifs comprenant un module matériel fonctionnant comme un noyau de commande d'actifs. Ce noyau de commande d'actifs inclut un petit noyau matériel intégré dans un système cible sur puce qui permet d'établir un point de confiance à base matérielle sur le dé de silicium. Le noyau de commande d'actifs peut être utilisé comme racine de confiance sur un dispositif client dans la mesure où il présente des caractéristiques qui le rendent difficile à manipuler frauduleusement. Le noyau de commande d'actifs est en mesure de générer un identifiant spécifique pour un dispositif et de participer au suivi du dispositif et à son alimentation en ressources par un canal de communication sécurisé avec un appareil. Cet appareil comporte généralement un module sécurisé qui met en mémoire cache et distribue des données d'alimentation à l'un de multiples agents qui sont connectés au noyau de commande d'actifs, par exemple une chaîne de fabrication ou une session de programmation après fabrication.
