| English Abstract | 基于角色的访问控制模型的研究工作近年来得到了广泛的重视。但主要工作均立足于与时间特性无关的其他方面。本文形式化描述了一个引入时间后的角色访问控制模型。在该模型中对原有授权约束进行了时间扩充。提出了相应算法解决了时间授权约束和会话的状态转变问题。同时分析了模型的一致性状态并讨论了一致性状态维护问题。 |
| Abstract | The research work of RBAC is greatly emphasized in recent years. But the main work focus on some other characters which has nothing to do with the time character. We describe a RBAC model with time character called TRBAC, in which, we extend the fonner constraint so that it can describe the time character and we point out some algorithms to solve state change problem of the time-constraint and the sessions. We also analysis the consistent state of the model and discuss the problem to maintain the consistent state. |
