| 摘 要： | 基于角色的访问控制是一种高效安全的访问控制机制，但是RBAC2001建议标准中没有提出根据单位特征、功能特征和数据特征来细化控制角色指派的详细方法。本文结合RBAC模型思想和大型企业信息系统的实际需求，对核心RBAC模型进行细粒度的扩充，在单位、功能、数据等维度对模型进行了细化，并给出了实例应用，有效地解决了大型企业信息系统的安全访问控制难以细化的问题。

| Abstract: | Role-Based Access Control(RBAC) is a kind of access control mechanism which is secure and high perform- ance.But the standard for RBAC2001 model does not give the method which based the character of department,func- tion and data to control the role assignment.Combining with the idea of RBAC model and the requirement of large-scale enterprise information system,the article make fine grain extension on Core RBAC model,and thinning the role assign- ment in the dimensionality of department,function and data.At last,this article gives practical application of the mod- el,and resolves effectively the question that secure access control difficult to thin in large-scale enterprise information system. |
