Abstract
A computing device includes a bus controller and an endpoint device that are in communication over an internal bus. The bus controller initiates a discovery message to the endpoint device requesting a computational value based on the discovery message, wherein the computational value is generated by the endpoint device using a predefined algorithm and the discovery message includes a preconfigured identification code associated with the bus controller. The bus controller receives a response from the endpoint device, which includes the computational value, when the endpoint device authenticates the controller based on the preconfigured identification code. If the bus controller successfully authenticates the endpoint device based on the computational value, the controller sends an acknowledgment message to the endpoint device and registers it as being owned by the bus controller. Otherwise, the bus controller sends a failure message to the endpoint device and logs it as being unmanageable by the controller.
