摘要
详细分析了某应用系统中分布式指控系统的复杂访问控制需求,指出了RBAC与TBAC在实际应用中的优势与不足,结合分布式指控系统的并行化任务处理特点以及流水线计算特点,建立了基于任务—角色的分布式指控系统访问控制D_TRBAC模型,并研究了D_TRBAC的具体实施。
Complex access control requirement of distributed command and control system in a certain great application system is analyzed in detail. The advantage and shortage of RBAC and TBAC in practice are demonstrated. Then according to the collateral-task and the pipelining characters of the distributed command and control system, D_TRBAC model is built, and the implement of D_TRBAC is studied.
