Abstract: An apparatus and method are described for authenticating extended service microcode updates. For example, one embodiment of a method comprises: storing extended service microcode update (MCU) in a memory of a processor; reading processor signature data, platform identification data, and processor extended service data from one or more registers of the processor; identifying MCU extended service period data based on processor signature data and platform identification data; determining whether to apply the extended service MCU on the processor based on a comparison between the MCU extended service period data and the processor extended service data.
