%X The emerging and rapid development of Multimedia Social Networks make information changes and shares a- mong users much more convenient, but the phenomenon of unauthorized distributions on copyrighted digital contents becomes more serious. Digital rights management is an open issue and key challenges in the open network. With regard to behaviors of digital contents share and dissemination among social network user nodes, a framework and its secure protocol for digital contents distribution were proposed based on a trusted attestation proxy party-enabling remote at- testation in MSN. I}he proposed DRM scheme was analyzed and compared with the typical ones available, and the re- sups denote that combined with the trusted computing-supported high-level security user terminals, the novel method implements enhanced security, trustworthy and controllable mechanism on digital copyrights protection, and meets the requirement for platform privacy protections.
