IPTV数字版权管理认证协议设计

摘要

By analyzing the state-of-art of IPTV and some related works at home and abroad, a security authentication protocol of IPTV digital rights management is proposed. Based on the basic process of IPTV on demand, the protocol adds the functions of user anonymity and mutual authentication, key management scheme, encrypted streaming media, user cert and license to digital rights management to provide a more complete authentication architecture for current IPTV technology which is lack of protection. The protocol has the advantages of simple design process, high security and flexible application. Experimental results show that the protocol is efficient in authentication security, system integrity and user experience.%通过对当前pPTV现状的分析以及国內外相关工作的研究,提出一种IPTV数字版权管理安全认证协议.协议在基本IPTV点播流程上,加入了数字版权管理中用户匿名和双向认证、密钥管理体系、加密流式媒体、用户证书以及许可证等功能,为目前缺乏保护的IPTV技术提供了一个较为完整的认证架构.该协议设计流程简洁,安全性证明简明,应用场景灵活.实验结果表明协议认证的安全性,体系的完整性以及用户体验都较好.
