摘 要: 跨域互操作的角色访问控制模型IRBAC2000(interoperability role based access control 2000)是一种通过动态角色映射实现域间授权访问的模型,该模型的角色映射过程中可能会出现映射冲突,容易引入安全风险。在该模型的基础上,针对不同的映射冲突问题,分别给出了相应的检测算法,降低了域间互操作的安全风险。
关 键 词: 计算机应用;跨域;角色映射;跨域互操作的角色访问控制模型2000;冲突检测

Abstract: The interoperability role based access control 2000 (IRBAC2000) is a model which can achieve inter-domain access authorization through dynamic role mapping. The mapping conflicts may occur in the role mapping process, and so it can introduce security risks easily. On the basis of this model, this paper gave the corresponding detection algorithms in response to these conflicts, which reduced the security risks of inter-domain interoperability.
