虚拟专用网技术及其在电力系统二次安全防护中的应用

Virtual private network technology and its application to secondary security protection of power system

鉴于虚拟专用网技术在电力数据通信网和电力系统二次安全防护中的重要地位, 介绍了隧道技术和认证加密等虚拟专用网核心技术, 并在此基础上, 对虚拟专用网技术在计算机网络安全防护中的应用进行了探讨。

In view of the importance of virtual private network(VPN)technology to power data communication network and the secondary security protection of power system,this paper describes such key techniques of VPN as tunneling technique,certification and encryption. On this basis,the application of VPN technology in the computer network security protection is approached.
