利用FreeS/WAN构建基于Linux的IPSec VPN安全网关

The Construction of Security Gateway of IPSec VPN on Linux by Using FreeS/WAN

VPN虚拟专用网(VirtualPrivateNetwork)是一种通过采用隧道、加密和身份认证技术来构建专用网络的技术。IPSec作为新一代网络安全协议,能够构建安全VPN,实现数据的安全通讯。本文在研究IPSec体系结构及实现方法的基础上,对Linux平台下IPsec协议的实现软件——FreeS/WAN的系统结构进行了深入剖析,给出了其配置、测试步骤和源码框架,并为Linux下的VPN构建提供了一个较为实用的示例。

VPN is through the use of tunnels,encryption and authentication technology to create a proprietary network technologies,IPSec,as a new generation of network security agreement to establish a secure VPN,the security of data communications.Based on the study of architecture and implementation of IPSec based on the Linux IPsec agreement on the structure of the system software-FreeS/WAN conducted an in-depth analysis, given its configuration, and source testing framework for building a Linux VPN provides a more practical examples.
