Multiple layers of protection isolate the Secure Enclave protected memory from the Application Processor. The Secure Enclave operates from a dedicated region of the device’s DRAM memory.

It follows the same design principles as the SoC does-a boot ROM to establish a hardware root of trust, an AES engine for efficient and secure cryptographic operations, and protected memory. The Secure Enclave is isolated from the main processor to provide an extra layer of security and is designed to keep sensitive user data secure even when the Application Processor kernel becomes compromised.
