摘　　要：针对传统的RBAC(Role-Based Access Control)模型无法灵活方便地用于车辆监控系统中的权限控制问题,提出一种多粒度RBAC模型的改进模型。引入角色分组和用户分组的概念,并允许同时对角色和用户授权,以及通过车主等身份确认权限等。对于可能出现的权限冲突,通过权限叠加算法加以处理。实验结果表明,该模型在大规模的车辆监控系统中,可以准确高效地完成权限检查。Aiming at the problem that traditional RBAC model cannot be flexibly used in permission control of vehicles monitoring system, we present an improved multi-granularity RBAC model.The model introduces the concepts of role grouping and user grouping and allows simultaneous authorisation on both the roles and the users,and validates the privileges by car user’s ID.Permission superposition algorithm is used to resolve the potential permissions conflict.Experimental result indicates that the model is able to complete the permission inspection accurately and efficiently in large-scale vehicles monitoring system.
