摘要
针对反应堆数字孪生体建模中常见的树形结构,以经典权限模型为基础,补充和完善该类型客体的访问控制策略,为反应堆数字孪生体建模过程中数据多级保护提供技术解决措施,提升信息的保密性。采用形式化语言描述,对树形结构中各节点的密级设置、授权规则和访问鉴权进行总结并给出定义。非信息安全专业的研究人员在数据建模过程中可方便应用,从而有效提升对孪生体数字资产的保护。
According to the tree structure applied on the reactor digital twins generally,this article improves the access control policy based on the classical permission model,which providing technical solutions for multi-level data protection and improving the confidentiality of information during the modeling process of reactor digital twins.Formal language is used to describe and summarize the definitions including the security level settings,authorization rules,and access authentication of each node in the tree structure.This makes it convenient for non information security professionals to apply in the data modeling process,effectively enhancing the protection of twin digital assets.
