针对于传统的基于角色的访问控制模型RBAC在实际应用中,由于其静态特性,很难对于系统中的用户权限进行动态管理,造成在角色指派和权限管理方面的一场。在阐释了用户信任计算方式后提出了改进模型——基于信任的动态访问控制模型T-DARBAC模型,构建了云平台下的访问控制架构。实验证明该模型在实际应用中能够对用户权限进行动态分配。
For the traditional role-based access control model RBAC in practical applications, due to its static characteristics, it is difficult to dynamically manage the user rights in the system, resulting in a role in the role assignment and rights management. After the user trust calculation mode is expounded, the improved model-T-DARBAC model based on trusted dynamic access control model is proposed and the access control architecture under the cloud platform is built. Experiments show that the model can dynamically assign user rights in practical application.
