Abstract: 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.

Abstract: A request associated with one or more privileges assigned to a first entity may be received. Each of the one or more privileges may correspond to an operation of an integrated circuit. Information corresponding to the first entity and stored in a memory that is associated with the integrated circuit may be identified. Furthermore, the memory may be programmed to modify the information stored in the memory that is associated with the integrated circuit in response to the request associated with the one or more privileges assigned to the first entity.
