Abstract: A computer system includes a volatile memory and at least one processor. The volatile memory includes a protected storage segment (PSS) configured to store firmware-authentication program code for authenticating firmware of the computer system. The at least one processor is configured to receive a trigger to switch to a given version of the firmware, to obtain, in response to the trigger, a privilege to access the PSS, to authenticate the given version of the firmware by executing the firmware-authentication program code from the PSS, to switch to the given version of the firmware upon successfully authenticating the given version, and to take an alternative action upon failing to authenticate the given version.
