Abstract
Methods and systems are provided for authenticating component(s) in connection with the use of a trusted graphics system. Techniques are provided for authenticating a graphics card in connection with a system that cryptographically secures content routed through a graphics pipeline, such that an application or device can indicate to the trusted graphics platform that the application or device is a trusted user of the trusted graphics platform, and such that the graphics platform can communicate to the trusted application or device that the graphics platform may be trusted by the application or device.
