OMA Digital Rights Management V2.0
The OMA DRM enables content providers to grant permission for media objects that define how they should be consumed. The DRM system is independent of the media object formats and the given operating system or run-time environment. The media objects controlled by the DRM can be a variety of things: games, ring tones, photos, music clips, video clips, streaming media, etc. A content provider can grant appropriate permissions to the user for each of these media objects. The content is distributed with cryptographic protection; hence, the Protected Content is not usable without the associated Rights Object on a Device. Given this fact, fundamentally, the users are purchasing permissions embodied in Rights Objects and the Rights Objects need to be handled in a secure and un-compromising manner.
The OMA DRM 2.0 Enabler Release defines the protocols, messages and mechanisms necessary to implement the DRM system in the mobile environment. It builds upon the OMA DRM 1.0 Enabler Release with significantly improved security and functionality for a robust, end-to-end DRM system that takes into account the need for secure distribution, authentication of Devices, revocation and other aspectsof the OMA DRM 1.0.
