Abstract
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.
