基于证据理论的无线通信系统安全风险评价

传统通信系统安全风险评估方法获取的判断矩阵是个体专家的意见,无法处理不确定问题,得到的评估结果较为主观、准确度差,为了解决该问题,提出了基于证据理论的通信系统安全风险评价模型。采用证据理论融合规则调整通信设备和光缆一级指标的判断矩阵,综合多位专家的意见,获取设备和光缆各指标的状态评分和指标权重,构建通信系统风险评估模型,最后通过仿真实验测试其性能,结果表明,该模型可以准确评估通信系统的风险等级。

Safety Risk Assessment of Communication System Based on Evidence Theory

the judgment matrix access security risk assessment method of traditional communication system is the individual experts, unable to deal with the uncertain problem, the assessment results are subjective, poor accuracy, in order to solve this kind of problem, put forward the communication system security risk assessment model based on evidence theory. The judgment matrix of evidence theory fusion rules of communication equipment and cable level indicators, a number of experts, access to equipment and cables of each index scores and index weights, system risk assessment model, finally through the simulation experiment to test its performance, results show that the model can accurately assess the risk communication system grade.
