摘要
针对已有跨域间密钥协商协议与IP多媒体子系统(IMS)会话建立过程不相匹配及安全性较差等问题,分析了IMS会话建立过程,研究了端到端信息传输的安全需求,提出一种改进的IMS跨域间认证密钥协商协议IKAAP,并进行了安全性分析。结果表明,改进后的协议能够保证终端用户在三网融合环境下实现端到端信息的安全传输。
Aiming at session process between cross-domain key agreement protocol and IP multimedia subsystem（IMS）does not match and security poor,process of IMS session establishment is analyzed,security requirements of end-to-end information transmission is studied,an improved IMS cross-domain key authenticated agreement protocol（IKAAP）is put forward,and improved protocol＇s security is analyzed.Result shows that the improved protocol can guarantee the end user in the triple play environment to realize the end-to-end security information transmission.
