Abstract
In accordance with some embodiments, a single trusted platform module per platform may be used to handle conventional trusted platform tasks as well as those that would arise prior to the existence of a primary trusted platform module in conventional systems. Thus one single trusted platform module may handle measurements of all aspects of the platform including the baseboard management controller. In some embodiments, a management engine image is validated using a read only memory embedded in a chipset such as a platform controller hub, as the root of trust. Before the baseboard management controller (BMC) is allowed to boot, it must validate the integrity of its flash memory. But the BMC image may be stored in a memory coupled to a platform controller hub (PCH) in a way that it can be validated by the PCH.
