基于P2P的数字版权管理系统体系及协议研究

P2P-based digital rights management system and agreement

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,提出了基于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与探讨。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,对体系工作的流程进行了深入探讨。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。

Based on the analysis of the P2P network models and digital lights management （DRM） technology on the basis of the system, based on P2P model of DRM system, this paper discusses on the system architecture and transmission protocol. Based on the system topology, it proposes a functional framework for the system, and which contents management, contents identification, and quality control mechanism to pay for the analysis and design. At the same time, digital contents life cycle and value chain based on the work of the system processes are conducted in-depth discussions. The system gives the upload and download digital contents, the realization of the P2P network model with the DRM technology integrated and effective system.
