Abstract:

Devices, systems, methods, and other embodiments associated with processing commands according to authorization are described. In one embodiment, a chip includes a secure module configured to store secure firmware, and to execute the secure firmware. The secure firmware prevents the secure module from at least partially processing a command that originated from an untrusted source. The chip also includes an unsecure module configured to store unsecure firmware, and to execute the unsecure firmware. The unsecure firmware permits the unsecure module to process a command having originated from an untrusted source. The chip is configured where the unsecure firmware is separately updateable from the secure firmware.
