摘要
传统的强制访问控制策略(MAC)可操作性、灵活性差,日益不适应分工明确、分布性广、实时性要求高的军事领域,基于任务-角色的访问控制策略(T_RBAC)结合了基于角色(RBAC)和基于任务(TBAC)访问控制的优点,应用性很广。在分析了强制访问控制思想后,将其引入基于任务-角色的访问控制模型中,构建了一种军用的基于任务-角色的访问控制模型,并对模型的性能作了简要分析。
The traditional mandatory access control tragedy （MAC）, which is weak in maneuverability and flexibility, can not fit well in the military field gradually, which is definitely divided into several posts, geographically widely distributed and high real-timely demanded as well. The task_role_based access control tragedy （T_RBAC） which combines advantages of both RBAC and TBAC has a good practicability. The spirit of MAC is analyzed and then introduced into a task_role_based access control model. At last, a task_role_based access control model for military use is built, and its capability is simply analyzed.
