Abstract

Abstract

In order to have a thorough understanding of the technical architecture of OMA DRM specification, and to actively promote creation of the Chinese DRM standard and application research of digital content protection technology, a systematic approach of OMA DRM is presented. The following functions of the latest release of OMA DRM2.0 are analyzed: rights object acquisition protocol, security model, architecture, content format and rights expression language. Then, these features are synthesized to present a complete working mechanism of OMA DRM: working flow and principle of OMA DRM. Finally, the capabilities of the latest release are analyzed by presenting the main difference between OMA DRM2.0 and OMA DRM1.0, and the limitations of OMA DRM2.0.
