Method and device for identifying key nodes of combat system network

Abstract

The invention relates to the field of combat system key node identification, in particular to a combat system network key node identification method based on a killing chain. Modeling the plurality of nodes and the plurality of edges, and constructing a combat system network model based on a node model and an edge model; constructing a plurality of killing chain models based on the target node; performing multiple Monte Carlo sampling on the combat system network to determine a combat system network state vector; based on a Ullmann algorithm, determining a plurality of killing chains containing a specific target in the combat system network; searching a target node in a plurality of killing chains, and counting the number of the killing chains where the node is located; measuring the killing chain to obtain importance values R of a plurality of target nodes, and determining key nodes based on the importance values R; according to the method, the node importance index can reflect the influence of heterogeneous combat factors such as performance differences of different devices and importance of attacking targets, so that reasonable and effective identification of key nodes is realized.

Description

technical field [0001] The invention relates to the field of identification of key nodes of a combat system, in particular to a method and device for identifying key nodes of a combat system network based on a kill chain. Background technique [0002] With the in-depth application of modern high-tech in the military field, the operational coordination and coupling relationship between weapons and equipment is becoming stronger and stronger, and the war mode is rapidly changing from "platform-centric warfare" to confrontation between the two combat systems. Effective identification of key nodes in the combat system can on the one hand guide actual combat operations from the perspective of attack and achieve effective attacks on the enemy system; on the other hand, it can also identify vulnerable nodes of our system from the perspective of defense. Provide guidance for system defense and optimization. [0003] The combat system can be described based on the network model. At ...

Problems solved by technology

Because the former method uses a general network centrality index, it does not reflect the specific combat process, and the interpretability of the obtained results is poor and does not necessarily conform to the actual situation; although the latter method is derived from the "OODA loop "The angle of view considers the operational process and the dependencies between operational nodes, but it does not reflect the influence of heterogeneous factors such as the mission success rate of different equipment in the combat system network and the importance of target nodes on the key nodes of the system, and there are certain defects.
