Abstract

Digital rights management(DRM) systems are used to control the use and distribution of copyrighted content. OMA specification creates devices collection of domain, and the use of contents is free in this domain. Domains are created and managed directly by the RI(rights issuer) that issues rights to the domain. In this paper, we propose a new rights object acquisition protocol(ROAP) for DRM and a efficient key distribution protocol. The proposed ROAP provides billing functionality for purchasing rights via network operator which was not considered in OMA DRM 2.0 specifications.
