摘　　要：现有入侵攻击源定位方法由于数据库不够完善,导致定位精度与激光通信网络攻击检测精度较低。为此,提出基于知识图谱的激光通信网络入侵攻击源定位方法。构建激光通信网络知识图谱,分析激光通信网络的特性。利用层次聚类算法对网络样本进行攻击检测,其中包括层次聚类算法、迭代聚类算法、最优方案选取以及网络攻击检测四部分,得出激光通信网络中的异常数据。根据异常数据检测结果,通过三边定位方法初步定位异常数据位置。最后,通过改进粒子群优化算法实现激光通信网络入侵攻击源定位。试验结果表明,所提方法能够准确定位攻击源的坐标位置,并且激光通信网络攻击检测准确率较高。The existing intrusion attack source location methods have low location accuracy and laser communication network attack detection accuracy because the database is not perfect. Therefore, a laser communication network intrusion attack source location method based on knowledge map is proposed. The knowledge map of laser communication network is constructed, and the characteristics of laser communication network are analyzed. The attack detection of network samples is carried out by using hierarchical clustering algorithm, including hierarchical clustering algorithm, iterative clustering algorithm, optimal scheme selection, and network attack detection. The abnormal data in laser communication network is obtained. According to the abnormal data detection results, the abnormal data location is preliminarily located by trilateral positioning method. Finally, the intrusion source location of laser communication network is realized by improving particle swarm optimization algorithm. Experimental results show that the proposed method can accurately locate the coordinate position of the attack source, and the laser communication network attack detection accuracy is high.
