Secure Mobile DRM Solution on Fair Charging

Based on the research of mobile digital rights management (DRM), a charging fair solution of secure mobile DRM for applications in 3G wireless communication networks is proposed. The secure mobile DRM solution guarantees the security and integrity of the digital contents and right objects, and prevents the right issuers cribbing the digital contents. Furthermore, a practical fair payment protocol without TTP is presented and used in this mobile DRM, it leads to cost reductions of protocol implementation and involving exchange. At last, the security analysis and efficiency comparison are presented.
