摘　　要：为提高电力通信网的防御性能,缩短其在面对未知威胁时的响应时间,本文设计了一种电力通信网络终端未知威胁协同防御方法。通过对终端威胁入侵成功概率分析,采用威胁匹配矩阵模型确定网络威胁指数;计算电力通信网络特征路径长度的基础上,设置区域协同防御目标变量及约束条件,获取任意不良数据在电力通信网络中的最大标准残差。针对未知威胁设计协同防御模型,获得计算攻击与防御策略的均衡模型。测试该防御方法在不同攻击下的响应时间,实验数据表明,该方法的防御响应时间虽随距离长度的增加而增加,但整体用时均较少,且频率终止响应时间均小于80ms,说明该方法的防御效果较好。In order to improve the defense performance of electric power communication network and shorten its response time when facing unknown threats,a cooperative defense method of terminal unknown threats in electric power communication network is designed.Based on the probability analysis of terminal threat intrusion,the threat index is determined by threat matching matrix model,and the characteristic path length of electric power communication network is calculated,the target variables and constraints of area cooperative defense are set to obtain the maximum standard residuals of any bad data in power communication network.A cooperative defense model is designed for unknown threats,and the equilibrium model of computational attack and defense strategy is obtained through calculation.Test the response time of the defense method under different attacks.The experimental data show that although the defense response time of this method increases with the increase of distance length,the overall time is less,and the frequency termination response time is less than 80ms,indicating that the defense effect of this method is good.
