摘要
虚拟专用网 (IP -VirtualPrivateNetwork ,IP -VPN)是解决企业利用公共网络实现内部数据安全通信的一种技术 ,根据其实现的方式在网络分层中所处的地位可分为应用层 (如SOCKS)、IP层 (IPSEC)和数据链路层 (如L2TP、PPTP)VPN三种。由于VPN设备本身具有保密的特征 ,因此往往难以获得有关其实现的技术细节。IPSEC已成为IP -VPN的一个标准。对IPSEC实现的原理和方法进行了分析讨论 。
The IP-VPN technology is applied to provide secure communications for enterprises.According to the functions in the layered network architecture, three strategies can be used to implement it, i.e. are application layer(such as SOCKs), data link layer(such as L2TP, PPTP) and IP layer (IPSEC). Due to the security feature of the VPN device it is difficult to obtain the implementation details. IPSEC has become a standard of IP-VPN.This paper analyzes the principle and methods of implementing IPSEC, and proposes a special mechanism for implementing IPSEC.
