基于IPSec的VPN实现与安全研究

Implementation and Security Research of VPN Based on IPSec

首先介绍了虚拟专用网的基本概念,接着全面描述了IPSec作为工作在网络层的安全协议,灵活地将加密、认证、密钥管理和访问控制等结合在一起,为Internet提供了一个标准的、安全的网络环境.最后在此基础上详细论述了基于IPSec的VPN的实现,并研究其安全性.

This thesis firstly introduces the basic concept of VPN,and then entirely describes IPSec is the security protocol that works under the network layer.It combines flexibly encryption,authentication,key management and access control to provide a standard for Internet network security network environment.It finally analyses the implementation of the VPN based on IPSec and research the security of it.
