SEAMLESS FIRMWARE UPDATE MECHANISM

Abstract:

An apparatus is disclosed. The apparatus comprises one or more processors to receive a request to perform a firmware update at a device, prepare a second trusted compute base (TCB) layer for the firmware update, generate a first compound device identifier (CDI) associated with a first TCB layer to be used by the second TCB layer to attest an operational state of the first TCB layer prior to applying the update and generate a second CDI associated with the first TCB layer to be used by the second TCB layer to attest the operational state of the first layer after the update has been applied and perform the firmware update of the second TCB layer.
