摘要
本文介绍了TD-MBMS技术现状与发展,对TD-MBMS网络中的业务和内容保护进行了研究;从SRTP协议和MIKEY协议的原理入手分析,对TD-MBMS的业务和内容保护方案中进行了深入的剖析;研究3GPPTS33.246、IETF RFC3711和IETF RFC3830等规范,给出基于MIKEY协议的分层密钥体系;最后得出结论,在TD-MBMS业务的业务和内容保护方案中,使用SRTP协议的封包架构提升加密套件互通性,使用MIKEY协议进行密钥管理,把关通信信令的安全。
This paper introduces the present statue and development of TD-MBMS, studies the traffic and content protection transmitted in the TD-MBMS network, analyses the principle of SRTP and MIKEY protocols,and deeply explained the traffic and content protection scheme of TD-MBMS. The standards such as 3GPP TS33. 246, IETF RFC 3711 and IETF RFC 3830 are studied and the hierarchical key architacher based on the MIKEY protocol are presented. Finally,encapsulation packet of SRTP used for improving the connection between encrypt groupwares,MIKEY protocol used for key management and guarantee the safety of the communication signaling are concluded.
