  • Firmware module execution privilege
    Patent number: 10268822
    Abstract: According to one example for verifying firmware module execution privilege, a firmware is booted on a processor. At least one firmware module in the firmware marked as a test module is identified, and verification with a production public key of metadata associated with the firmware is attempted. In an example, in the event that the metadata verifies successfully with the production public key, the firmware boot is halted when the processor determines that access to a video interface is available, and a user is alerted that a test module has attempted execution in a production firmware.
