Design and implementation of mobile security system based on IPSec VPN
基于IPSec VPN的移动安全系统的设计与实现

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.
