Role-based access control(RBAC) system has been widely used in data security because of its good flexibility and security, wherein RBAC dominates the field of access control. However, the process of establishing RBAC roles is complex and time-consuming, which hinders the development and application of this field. Recently, the introduction of expert interactive q&a algorithm based on attribute exploration has greatly reduced the complexity and time-consuming of RBAC role building process. However, when attributes increases, algorithm will face challenges that the time complexity will explode exponentially with the increase of attributes. To cope with above problems, this paper proposes a hierarchical assisted exploration model of RBAC under attribute-based exploration expert interactive q&a algorithm framework from the view of reducing time-consuming of overall and single role engineering. This model not only avoids time-consuming process of single role requirements, but also reduces time-consuming process of whole role establishment from the overall architecture perspective.
