摘　　要：针对智能仪表典型功能模块和安全需求,文章设计了策略重叠消除和冲突消解相分离的融合方法框架,实现了对安全策略的形式化建模和属性特征提取。文章综合权衡安全防护能力、风险缓解程度和仪表资源受限等多方面因素,并考虑网络通信安全策略和控制行为动作安全策略在融合过程中的属性模糊偏好差异,得出最优的安全防护策略部署方案,通过仿真实验验证了所提方案的可行性和有效性。文章通过模糊多目标决策和优先级选择的方式,实现了智能仪表功能安全策略与信息安全策略融合过程。Aiming at the typical functional modules and security requirements of instruments,this paper designs a coordination framework that eliminate strategy overlap and resolve strategy conflicts.Based on the framework,the attributes of the security strategy are extracted and the formal modeling is completed.Then,this paper strikes a balance among security protection capabilities,risk mitigation degrees,instrument resource constraints and various factors comprehensively,and considers the difference of fuzzy preference of network communication security strategy and control behavior security strategy in the strategy integration process.Furthermore,the optimal deployment plan of security protection strategy is drawn.Finally,simulation experiments verify the feasibility and effectiveness of the proposed approach.In this paper,through a combination of fuzzy multi-objective decision-making and priority selection,the integration process of functional safety strategy and information security strategy for intelligent instrument is realized.
