    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: A method and apparatus of a device that enables a user to participate in a secure instant messaging session by starting with a low security connection before switching to a high security connection is described. The device concurrently establishes a low security connection and a high security connection with a remote participant of the secure instant messaging session. The device sends a first message to the remote participant through the low security connection while the high security connection is being established. The device further determines whether the high security connection is established. If the high security connection is established, the device can send a second message to the remote participant through the high security connection. If the high security connection is not yet established, the device can send the second message to the remote participant through the low security connection.
