摘    要:FMC网络中的IP语音通信是极为重要的一种基础业务,具有广泛应用前景。然而,在面对复杂开放的全IP融合网络环境时,VoIP缺少可靠的安全保障,面临各种各样的安全威胁。同时,固定移动融合网络环境下,需要更为快速的安全认证和加密技术作为系统应用安全的基础。对于FMC网络中的VoIP应用来说,涉及2个最为关键的应用层协议,即IETF制定的用于会话初始的SIP(Session Initial Protocol)协议以及用于传输媒体流的RTP(Real Time TransportProtocol)协议,SIP协议采用文本形式表示消息的词法和语法,RTP协议信息流直接在网络上传送,目前存在很大的隐患和安全威胁。文章主要针对FMC网络环境下的VoIP应用安全做前瞻性的研究,设计适用于VoIP信令协议(如SIP)及媒体协议(如RTP)安全防护的短签密方案。

Abstract:In FMC networks,IP Voice communication is extremely important as a basis for business,and has broad application prospects.However,in the face of complex open all-IP converged network environment,VoIP,the lack of reliable security,face a variety of security threats.At the same time,fixed-mobile convergence network environment needs technology of faster and more secure authentication and encryption as the basis for the system application security.For VoIP applications in the FMC networks,involving two of the most critical application layer protocol,IETF SIP(Session Initial Protocol) for the Session Initiation Protocol by using the text form to express the message of lexical and syntax,and RTP(Real Time Transport Protocol) protocol is directly transmitted over network for the transmission of media stream,at present,there is great potential and security threats.With FMC network environment,and for security of VoIP applications,it does a prospective study,designed for VoIP signaling protocols such as SIP and media protocol RTP security short signcryption scheme.
