摘要
抗毁性能的建模与分析是研究网络信息安全的一个重要内容。基于复杂网络的动力学理论构建了舰船通信网络的抗毁模型。采用介数中心性和度中心性识别舰船通信网络的重要节点,得出在发起确定性攻击后网络抗毁性能和网络通信质量的变化规律。通过抗毁仿真实验,对舰船通信网络的级联失效过程进行分析,得到了初始负载系数、容量系数和网络节点特性与级联失效破坏程度之间的关系。该研究对提高舰船通信网络的抗毁性和安全性提出了新的思路。
Modeling and analysis of invulnerability is one of the important contents in the study of information security.In this paper,the invulnerability model of ship communication network is constructed based on the dynamic theory of complex networks.The important nodes of ship communication network are identified by betweenness centrality and degree centrality,and the changes of network invulnerability and network communication quality after launching deterministic attacks are obtained.Through the invulnerability simulation experiment,the cascading failure process of the ship communication network is analyzed,and the relationship between the initial load coefficient,capacity coefficient,node characteristics and the consequences of cascading failure is acquired,which provides a new idea to improve the invulnerability and security of the ship communication network.
