Abstract
Systems and methods are disclosed for enabling access to a protected hardware resource. A hardware component includes at least one protected hardware resource. A unique hardware ID and a unique cryptographically secure or randomly generated enable value (EV) are integrated in the hardware component at the time of manufacturing. At run-time, special software generates or receives from an external source an enable register (ER) value and a comparison is made with the stored enable value. If the ER value and the EV match, access to the protected hardware resource is allowed.
