摘要： A system on chip includes a memory, a main processor that runs an operating system, and first Intellectual Properties (IPs) that perform respective processing operations. The main processor operates to copy target firmware to the memory using a firmware loader, using a hypervisor, block access of the main processor and the first IPs to the target firmware before verification of the target firmware, and using the hypervisor, grant access to the target firmware by a target IP among the first IPs that corresponds to the target firmware after the verification of the target firmware.

摘要： An integrated circuit includes a system memory, a security processor and a non-security processor. An attack against the integrated circuit is made more difficult based on using a key generated by the security processor. The security processor, as an example, reads a program image from the system memory and generates the key based on the program image. In some instances, a dedicated communication channel is provided for communication between the non-security processor and the security processor. The dedicated channel may be used to provide the key to the non-security processor for performance of a security operation.
