基于IPSec VPN的移动安全系统的设计与实现

为解决移动网络与固定IP网络之间跨网域的VPN安全接入问题，提出并实现了一种新型的基于IPSec VPN的移动安全系统。该系统在基于IPSec协议的虚拟专用网技术和远程访问服务的基础上，建立了一套完善的基于智能卡和X.509证书进行身份认证的机制，并且具有统一的安全信息服务平台。实验结果表明，该系统能够实现固网信息安全无缝地移动扩展。

Design and implementation of mobile security system based on IPSec VPN

To solve the security problem of using Virtual Private Network (VPN) technology to connect mobile networks and fixed-IP networks, this paper presented and achieved a new type of mobile security system based on IPSec VPN. This system, on the basis of IPSec VPN and remote access service, establishes a complete authentication mechanism based on smart card and X.509 certification, and has a unified security information service platform. At last, the results of the experiment show that the system can spread the information of the fixed-IP networks safely and seamlessly in mobile networks.
