摘要： 在分析了P2P网络模式和数字版权管理(DRM)技术体系的基础上，提出基于P2P模式的DRM系统体系，并对系统体系结构和传输协议进行了研究和探讨。基于体系的拓扑结构，提出了体系功能框架，并对其中内容管理、内容标识、付费机制和质量控制进行分析和设计。同时以数字内容的生命周期和价值链为依据，对体系的工作流程进行了深入的探讨。给出了体系的数字内容上传和下载协议，实现了P2P网络模式与DRM技术体系的有效集成。

Abstract: This paper discusses a digital rights management(DRM) system applicable to P2P network, and advances its systematic architecture and basic protocol. The P2P-based DRM architecture includes topological structure, functional assignment and working flow, and focuses on the content management, content identification, royalty payment and quality control technologies. It puts forward its digital content uploading and downloading protocols, achieving an effective integration of P2P model and the DRM technologies.
