在研究了强制访问控制MAC、自主访问控制DAC、基于角色的访问控制RBAC、基于任务的访问控制TBAC和基于任务-角色的访问控制T-RBAC之后,结合个人网络的特点,提出了一种适合于个人网络联盟环境的基于任务-角色的改进型访问控制模型PN_T-RBAC。
After researching mandatory access control MAC, autonomous access control DAC, role-based access control RBAC, task-based access control TBAC and task-role-based access control T-RBAC, combined with the characteristics of personal network, Task-role-based Improved Access Control Model PN_T-RBAC in Personal Network Environment.
