Recently, the open mobile alliance (OMA) has been set to define open DRM technologic specifications to protect copyrighted content against piracy, unauthorized use and distribution over mobile networks. This paper proposes an efficient OMA DRM v2.0 ROAP for protecting a rights object for a device. Our proposed ROAP can offer a more efficient DRM system for future mobile networks.
