基于IPsec VPN的实现

摘要

this paper is a brief introduction of fundamentals and implementations of the virtual private network (VPN),a comparison between characteristics and technologies of the traditional and based on IPsec VPN.Through studying IPsec, we presented a method of designing end-to-end VPN system based on combined SA of IPsec, and analyzing of its security.%介绍VPN的基础和实现,并比较了常规与基于IPsec的VPN特性及技术.通过研究IPsec,我们提出了设计端-端VPN系统用IPsec的安全关联SA的做法,而分析它的安全特性.
