    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.

    Abstract: In an embodiment, a system is provided in which the private key is managed in hardware and is not visible to software. The system may provide hardware support for public key generation, digital signature generation, encryption/decryption, and large random prime number generation without revealing the private key to software. The private key may thus be more secure than software-based versions. In an embodiment, the private key and the hardware that has access to the private key may be integrated onto the same semiconductor substrate as an integrated circuit (e.g. a system on a chip (SOC)). The private key may not be available outside of the integrated circuit, and thus a nefarious third party faces high hurdles in attempting to obtain the private key.

    Abstract: Techniques are disclosed concerning secure access to data in a computing device. In one embodiment, a computing device includes a communication interface, a memory, a memory controller, and a security processor. The communication interface may communicate with a different computing device. The security processor may generate a host key in response to a successful authentication of the different computing device, and then encrypt a memory key using the host key. The security processor may also send the encrypted memory key to the memory controller, and send the host key to the different computing device. The host key may be included by the different computing device in a subsequent memory request to access data in the memory. The memory controller may, in response to the subsequent memory request, use the included host key to decrypt the encrypted memory key and use the decrypted memory key to access the data.
