摘要
传统舰船通信网络节点安全性评估准确率较低,对此提出新型多数据源的舰船通信网络节点安全态势评估方法。引入节点易损性容忍概念,计算当前舰船网络节点的最大易损性容忍率,判断通信节点易损类型,对当前舰船所使用的3类通信网络节点拓扑结构分别进行节点安全态势分析,根据计算结果评估当前状态,实现通信网络节点安全态势的整体评估。实验数据表明,提出的多数据源舰船通信网络节点安全评估较传统评估方法相比,节点传输安全性指标评估准确率提高15%,节点路径契合率指标评估准确率提高22%,可以有效提高节点评估准确度。
the traditional warship communication network node situation overall assessment method for evaluating the accuracy is low, have put forward new multiple source communication network node security situation assessment method of ships. Introducing node tolerance mechanism of vulnerability, calculate the current ship nodes the biggest vulnerability tolerance rate, vessel network communication node vulnerability analysis algorithm is put forward, judging vulnerability communications node type, on the current ship used by node topology respectively for three kinds of communication network security situation analysis, according to the calculation results to assess the current state, to realize communication network node of the security situation in the overall evaluation. Experimental data show that the proposed multiple source warship communication network node compared to more traditional safety assessment, node transport security index evaluation accuracy increased by 15%, the node path fit index evaluation accuracy 22%, can effectively improve the node evaluation accuracy.
