Abstract
In one aspect, an embedded controller (EC) in a device may receive a firmware update for another component in the device and determine whether the firmware update has been previously applied at the component. If the firmware update has not been previously applied, the EC may assign an identifier to the firmware update and digitally sign the identifier. The EC may then provide the firmware update and the digitally-signed identifier to the component so that the component may apply the firmware update.
