Abstract: A base key that is stored at a device may be received. A network identification may further be received. A device identification key may be generated based on a combination of the network identification and the base key. Furthermore, the device identification key may be used to authenticate the device with a network that corresponds to the network identification.

Abstract: A base key that is stored at a mobile device may be received. A first dynamic key that is based on the base key may be generated. First transaction data corresponding to a first transaction associated with the mobile device may be received. Furthermore, the first dynamic key may be updated to generate a second dynamic key based on a combination of the first dynamic key and the first transaction data corresponding to the first transaction. Authentication of a second transaction associated with the mobile device may be requested based on the second dynamic key.

Abstract: A container corresponding to executable code may be received. The container may be executed in a secure computation environment by performing one or more operations specified by the executable code of the container. An instruction to terminate the executing of the container may be received from a high level operating system (HLOS) that is external to the secure computation environment. A determination may be made as to whether the container is associated with a preemption privilege and the executing of the container may be terminated after receiving the instruction from the HLOS based on the determination of whether the container is associated with the preemption privilege.

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.

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.
