An embodiment of a graphics apparatus may include a graphics processor including a kernel executor, and a security engine communicatively coupled to the graphics processor. The security engine may be configured to create a kernel security key, encrypt an executable kernel for the kernel executor in accordance with the kernel security key, and share the kernel security key with the graphics processor.

Graphics processor with encrypted kernels

Apparatus and method for scalable content protection. For example, one embodiment of an apparatus comprises: cryptographic management circuitry to securely store one or more keys associated with one or more media apps/applications; a plurality of processing engines, each processing engine comprising circuitry to process media content of the one or more media apps/applications; and a scheduler to schedule processing of the media content by the processing engines; wherein the cryptographic management circuitry is to restore a first cryptographic state including a first key associated with a first media app/application and/or first media content responsive to a request to process the first media content on a first processing engine.

System and method for content protection in a graphics or video subsystem

Apparatuses, methods and storage medium associated with single pass parallel encryption are disclosed herein. In embodiments, an apparatus for computing may comprise an encryption engine to encrypt a video stream. The encryption engine may comprise a plurality of encryption pipelines to respectively encrypt a plurality of video sub-streams partitioned from the video stream in parallel in a single pass as the video sub-streams are being generated. The plurality of encryption pipelines may use a corresponding plurality of multi-part encryption counters to encrypt the corresponding video sub-streams as the video sub-streams are being generated. Each of the multi-part encryption counters used by one of the encryption pipelines may comprise a sub-portion that remains constant while encoding the corresponding video sub-stream, but the sub-key is unique for the one encryption pipeline, and differs from corresponding sub-portions of the multi-part encryption counters used by the other encryption pipelines. Other embodiments may be disclosed or claimed.
