基于IPSec的VPN技术的应用研究

摘要

IPSec VPN是采用IPSec协议来实现远程接入的VPN技术,极大地提高了TCP/IP协议的安全可靠性.文中首先对VPN、IPSec技术进行了介绍,分析了IPSec VPN的特点,对IPSec协议的体系结构、工作模式等进行了研究,给出了IPSec 的具体实现步骤和方法,并通过IPSec VPN技术,提出了一个实现内网跨公网安全可靠传输数据的具体方案,结果证明了该技术的可行性和可靠性.总之,IPSec VPN保证在Internet网络传输数据安全性的基础上,节省了大量的网络费用.%IPSec VPN is VPN technology which uses the IPSec protocol to realize remote access .greatly improve the safety and reliability of the TCP / IP protocol. Firstly introduced VPN,IPSec technology,analyzed the characteristics of IPSec VPN,IPSec protocol architecture, operating mode and so on .gave the IPSec steps and methods, and through the IPSec VPN technology, presented a network implementation of a safe and reliable transmission of data across a network scheme,the results demonstrate the feasibility and the reliability of the technique. In conclusion,IPSec VPN ensured the data security in Internet network transmission and save a lot of cost.
