A new RBAC model named H-RBAC model is presented. H-RBAC model imports integrated inheritance to realiz the relationship between local role and global role and completes access control by session diffluence.

由于在满足目前大量存在的商业和政府部门系统安全需求方面显示了极大的优势，因此，它作为传统访问控制的替代和补充引起了广泛的关注[1]。

The static model describes the relationship among user, permission and role and imports integrated inheritance to actualize the relationship between local role and global role. The dynamic model completes access control by session diffluence based on the static model. The actualization for the model is researched based on the analysis of the content and the rule of the model.
