Abstract: This paper presents an extended model of RBAC with negative authorization and permission hierarchy and analyzes the conflicts due to negative authorization.It uses OWL-DL to represent the extended model and shows how to use an OWL-DL reasoner to detect the potential conflicts in the extended model.

Key words: Role Based Access Control(RBAC), Web Ontology Language(OWL), conflict detection

摘要: 提出带负授权和权限层次的扩展RBAC模型并分析模型中由负授权引起的冲突。用OWL-DL表示该扩展模型并说明如何使用OWL-DL推理引擎检测扩展模型中潜在的冲突。

关键词: 基于角色的访问控制, Web本体语言(OWL), 冲突检测
