基于MAPsec的MAP信令安全机制研究

Study of MAP Signaling Security Mechanism based on MAPsec

移动应用部分(MAP)协议是移动通信网络的信令协议,由缺乏安全保护的七号信令承裁。MAP安全(MAPsec)协议为传输MAP消息提供了安全保证。研究了MAPsec协议的网络模型、保护模式、消息结构及消息流程,对网络单元的安全策略数据库的参数设置提出了改进方案。

Mobile Application Part （MAP） protocol is the signaling protocol in mobile networks, which is carried by No.7 signal lacking of security guarantee. MAP Security （MAPsec） protocol provides security guarantee for transmitting MAP message. In this article, the network model, protecting mode, message structure and message procedure are studied, and an improved solution for .configuring the parameters in the security policy database of network elements is proposed.
