FLEXIBLE CONTENT PROTECTION SYSTEM USING DOWNLOADABLE DRM MODULE

摘要

A secure platform is enabled in which DRM modules can be downloaded and securely installed onto a consumer electronic device, such as a TV. Downloadable DRM solutions are supported for CE manufacturers. The problem of making downloadable DRM modules operate securely on a trusted generic hardware platform without compromising the security of DRM systems is addressed. The downloadable DRM solution uses secure trusted computing-based mechanisms thereby enabling a service provider to perform remote static and dynamic(run-time) attestation of the downloaded DRM module and DRM license in the media device and of content protection application(CPA).
