摘要
InternetVPN是专用网家族的最新发展。基于IPSec(IP安全协议)的VPN被广泛看好。该文在研究IPSec协议框架和Linux操作系统的基础上,提出了通过改造Linux内核以及在操作系统原来的TCP/IP协议栈上添加IPSec的实现方案,并对具体实现中的关键技术作了进一步的研究。
As one main research focus of network security,VPN puts forward a new solution of network-layer security architecture,and VPN based on the IPSec become more and more popular.In this paper,IPSec protocol architecture and Linux kernel structure are studied carefully.Then the paper presents the scheme of designing and implementing IPSec on the Linux-making changes to TCP/IP stack of Linux and implementing IPSec there.Also the key technique to accomplish this system is discussed in the paper in detail.
