Abstract

Devices, systems, methods, and other embodiments associated with processing commands according to authorization are described. In one embodiment, a chip includes an unsecure module configured to control unsecure firmware to process a command on data flowing in a datapath. The unsecure module processes commands from untrusted sources and trusted sources. The chip includes a secure module configured to determine if a command is from a trusted source and when the command is from a trusted source, the secure module controls secure firmware to further process the data flowing in the datapath. When the command is from an untrusted source, the secure module controls the secure firmware to not process the data flowing in the datapath.
