Abstract:
An SOC implements a security enclave processor (SEP). The SEP may include a processor and one or more security peripherals. The SEP may be isolated from the rest of the SOC (e.g. one or more central processing units (CPUs) in the SOC, or application processors (APs) in the SOC). Access to the SEP may be strictly controlled by hardware. For example, a mechanism in which the CPUs/APs can only access a mailbox location in the SEP is described. The CPU/AP may write a message to the mailbox, which the SEP may read and respond to. The SEP may include one or more of the following in some embodiments: secure key management using wrapping keys, SEP control of boot and/or power management, and separate trust zones in memory.
