安全数据网的构建及其在河南电力调度数据网应用

随着网络安全问题的日益突出,虚拟专用网VPN(Virtual Private Networks)技术将被广泛应用,VPN的基础安全协议——互联网协议安全IPSec(Internet Protocol Security)能为任何Inter-net通信提供安全保护协议。详细分析了IPSec协议的体系结构、工作模式和关键技术,并结合IPSec采用鉴别报头、封装安全有效负荷等加密技术特点,提出了实现安全电力调度数据网的方案和建议,给出了一种利用IPSec协议构造电力数据网安全VPN的模型,该模型既能保证数据在网络层的保密传送,同时也能对真实通信主机的IP地址进行屏蔽和保护。最后,详细介绍了IPSec在河南电力调度数据网的应用。

Construction of secure power data network and its application in Henan power data network

Along with network security becoming more and more serious,VPN(Virtual Private Networks) technology will be adopted more widely and IPSec(Internet Protocol Security) will become more popular,which could provide secure protection for any Internet communication.The system structure,working mode and key technology of IPSec are analyzed.With the encryption techniques of AH(Authentication Header) and ESP(Encapsulation Security Payload) applied in IPSec,a solution of secure power data network is proposed and a model for constructing power data secure VPN using IPSec is given,which ensures secure data transfer in network and amasks the IP address of real communication host.Its application in Henan power data network is introduced in detail.
