| 摘 要： | 针对网格复杂的访问控制需求，对现有的任务-角色访问控制模型进行改进，建立了角色-任务&角色的网格访问控制（G-R_TRBAC）模型。该模型在网格环境虚拟组织域间使用基于角色的访问控制策略(RBAC)结合证书管理系统，网格环境虚拟组织域内则是经过改进的任务-角色访问控制模型，满足了网格访问控制的多域性和动态性。

| Abstract: | Aiming at the complex demand of grid access control, the current task-role -based access control model for grid was improved and a new model based on role-task & role-based access control (G-R_TRBAC) was built. In G-R_TRBAC model, Role-Based Access Control (RBAC) combined with certification management system was applied in the virtual organizational domains of the grid environment. The virtual organizational domain of the grid environment was an improved model from the task-role-based access control model, which could meet the requirements of multi-domain and dynamic characteristics in the grid access control. |
