conditional cycle - 引用次数：3
To implement the timeliness of control rules, the term of conditional cycle based on cycle theory and tense RBAC are proposed, and we have defined role restriction, operating request and trigger in the form of conditional cycle expression.
为了实现控制规则的时态性,SCIAC模型在周期理论和时态RBAC的基础上提出了条件周期表达式,并以条件周期表达式为基础定义了角色约束、运行请求和触发器。
