基于PKI数字证书技术的电力监控系统控制指令身份认证方法

Identification Method of Control Instruction in Power Monitoring System Based on PKI Digital Certificate Technology

为了解决电力监控系统在边界防护与本质安全方面存在的问题,提出基于PKI数字证书技术的电力监控系统控制指令身份认证方法。设计电力监控系统核心功能,通过三因子RSA算法进行信息加密解密,生成公私钥对;利用PKI数字证书技术验证实体身份信息和公私钥匹配程度,实现电力监控系统控制指令身份认证。实验结果证明,该方法可以生成长度较小的密钥,减少监控系统运行负担,增强加密明文抗攻击能力,身份认证响应速率较快,且身份信息的错误接收率较低。

In order to solve the problems in boundary protection and essential security of power monitoring system,an identity authentication method based on PKI digital certificate technology is proposed.We design core functions of power monitoring system;conduct information encryption and decryption through three-factor RSA algorithm to generate public-private key pair.We also use PKI digital certificate technology to verify entity identity information and public-private key matching degree to realize the identity authentication of power monitoring system control instructions.Experimental results show that this method can generate small key to reduce the monitoring system,enhance attack resistance,has fast authentication response rate and low error receiving rate of identity information.
