Original Abstract Submitted
Embodiments are directed to providing integrity-protected command buffer execution. An embodiment of an apparatus includes a computer-readable memory comprising one or more command buffers and a processing device communicatively coupled to the computer-readable memory to read, from a command buffer of the computer-readable memory, a first command received from a host device, the first command executable by one or more processing elements on the processing device, the first command comprising an instruction and associated parameter data, compute a first authentication tag using a cryptographic key associated with the host device, the instruction and at least a portion of the parameter data, and authenticate the first command by comparing the first authentication tag with a second authentication tag computed by the host device and associated with the command.
