摘要
IPsec协议是IETF的Ipsec工作组制定的用于保护IP通信的标准协议。首先介绍IPsec协议;接着分析基于虚网卡机制和协议注册机制实现IPsec协议的FreeS/WAN软件;然后提出基于Netfilter机制实现IPsec协议;最后对这两种实现方案的结构进行了对比。
IPsec is a standard protocol made by IETF's ipsec working group, which is used to protect IP packet. In this paper, we first introduce IPsec protocol, and then analyze FreeS/WAN' s architecture, at last an IPsec implementation based on Netfilter is presented and a structure comparison of these two methods is given.
