一种面向云计算的任务—角色访问控制模型

针对云计算模式下用户访问安全的问题, 简单分析了基于角色和任务的访问控制模型的内容, 提出了一种基于云计算的任务—角色模型。该模型通过对角色和权限进行分类, 有效地解决了访问控制模型中的管理权限问题, 使得云计算服务商的权限分配得到了进一步改进。分析结果表明, 该访问控制模型可以进一步提高客体频繁访问的效率。

Model of cloud computing oriented T-RBAC

Based on problems of user access security in the cloud computing models, this paper made simple analysis of the content of task-role-based access control model and offered a model of cloud computing oriented T-RBAC, in which permissions and roles were classified, users were granted permissions by assigning them roles that have those permissions. This greatly simplified management of permissions in the access control models and further improved permission allocation of cloud computing service providers. The analysis results show that this access control model can further improve the efficiency of user frequent access.
