Conflict resolution method for security strategies for TSN industrial control system
In the area of time sensitive networking(TSN)industrial control system,the execution of security strategies may affect the normal operation of the business flow,leading to conflicts between system information security and function safety.Therefore,information safety and function security strategies in TSN industrial control system need to be deployed together and resolve conflicts between the two different safety strategies.To address the problem,a multi-step method for conflict identification and resolution with dual granularity fusion is proposed.The first step is to perform coarse-grained conflict identification and resolution based on strategy decision-making to obtain a set of conflict-free security strategies.The second step is to perform fine-grained conflict identification and resolution based on task scheduling,meeting the integrated requirements of business flow transmission security through strategy analysis and optimized closed-loop of delay prediction models.Finally,the effectiveness and feasibility of the proposed conflict resolution method are validated through experiments,which demonstrate that the proposed method can generate security strategies and corresponding security tasks that simultaneously meet the safety and real-time requirements of TSN industrial control systems.
