摘要 约束是RBAC模型中的一组强制性规则,是RBAC的重要组成。目前对约束的研究主要集中在关系约束、前提约束、数值约束、职责分离约束、势约束和时间约束等方面。时间约束是时间变化和角色许可的依赖关系的规则表示。该文就连续时间约束和周期时间约束进行了描述。约束的标准化、规范以及应用领域中提出的新的约束,都需要进一步研究。 Constraints are a set of imposed rules on role-based access control （RBAC）, and they are an important aspect of RBAC. Currently. The main research on constraints focus on relation constraint, precondition constraint, numerical constraint, separation of duties constraint, cardinality constraint, time constraint and so on. Time constraint denotes the rules of the time variety relate on the role enable. This paper describes the sequence time constraint and periodic time constraint. It＇s need to go deep into research on the standard of constraint, the pattern of constraint and the new constraint.
