Abstract

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.
