摘　　要：针对移动终端由于频繁迁移而带来的跨域访问中数据访问稳定与安全问题,提出一种支持细粒度授权的角色映射跨域访问委托模型。模型通过委托实现云服务器中管理节点对移动节点在申请服务时的交互困难问题进行监控管理,结合已有的量化角色技术,将映射角色集进行量化处理,实现细粒度的角色映射。实验结果表明,该模型具有较好的实用性和安全性,能够实现在移动终端跨域访问过程中终端节点的准确定位,降低了恶意节点申请的风险。A role mapping domain access delegate model which supports for fine-grained authorization is proposed to solve the data access stability and security issues in the cross-domain access of mobile terminal caused by frequent migration. The model makes it work through delegate in the cloud server that the management node monitors and manages the interac?tion difficulties when the mobile node applies for services. Combined with the existing technology of role quantification which quantifies the mapping roles, fine-grained role mapping is achieved. Experimental results show that this model good usability and security which achieves accurate positioning of terminal node in the mobile terminal domain access process and reduces the risk of malicious node application.
