工业控制系统重要节点的快速挖掘

Fast Identifying Important Nodes in the Industrial Control System

工业控制系统的可靠性、稳定性、抗毁性是工控系统安全首要问题。为提高系统安全性,提出了快速挖掘工业控制系统中重要节点的方法。针对工业化和信息化的深度融合的大型复杂工控系统,采用了基于复杂网络理论的重要节点评估思想。鉴于工业系统的特有节点分布不均衡性和社团性、有机结合度中心性、K-壳及社团扩散性,提出ER+方法,对实际挖掘样本进行分析。利用SIR动态分析试验,证明了该方法更加准确有效稳定。

Industrial control system reliability, stability, survivability is a primary security issues of the industrial control system. In order to improve system security, the method of fast identifying important nodes in the industrial control systems is introduced. Depth integration of industrialization and irrformationization of large and complex industrial control systems, the evaluation important nodes method is proposed based on the complex network theory. In the view of the uneven and community distribution of industrial systems, and blending organically the degree centrality,the K - shell and the community diffusion, tactfully put forward ER ＋ methods and analysis the actual mining samples. The experimental results of SIR dynamics suggest that the ER ＋ method is more accurate, effective, stable.
