Abstract:
A system architecture provides a hardware-based root of trust solution for supporting distribution and playback of premium digital content. In an embodiment, hardware root of trust for digital content and services is a solution where the basis of trust for security purposes is rooted in hardware and firmware mechanisms in a client computing system, rather than in software. From this root of trust, the client computing system constructs an entire media processing pipeline that is protected for content authorization and playback. In embodiments of the present invention, the security of the client computing system for content processing is not dependent on the operating system (OS), basic input/output system (BIOS), media player application, or other host software.

Claim (Index 17):
A client computing system comprising:\n a plurality of processor cores, at least one of the processing cores to execute a media player application and have a shared secret, the media player application to obtain encrypted content from a service provider server coupled to the client computing system over a network; a graphics engine to receive the encrypted content over a protected audio/video path at the full system memory bandwidth without compromising performance or security; and a security processor to execute firmware to provide attestation and key management operations, and have the shared secret, the security processor to provide a hardware-based root of trust between the client computing system and the service provider server, to obtain a key blob having an encrypted title key associated with the encrypted content from the service provider server, to control content processing on the client computing system, and to pass the encrypted title key associated with the encrypted content to the graphics engine; and wherein the graphics engine is to decrypt, decode, and decompress the encrypted content using the encrypted title key received from the security processor, to compose display image data, and to re-encrypt the display image data within the graphics engine; and pass the encrypted display image data to a display over a protected display interface.
