摘　　要：由于传统的访问控制机制在无人机网络资源类型众多且高速移动的情况下缺乏灵活性,所以为了实现无人机网络的授权变更与无人机间任务转移时的权限弹性管理,提出一种基于状态迁移的访问控制模型.该模型依据细化的客体资源访问性质来制定状态迁移规则,在无人机网络授权变更和权限转移时不仅实现了弹性权限管理,而且确保了主体优先级访问控制.在无人机网络环境中的实验结果表明,该方案的执行时间随主体和客体数量增加呈近似线性增长,且在无人机网络复杂的访问控制场景中是可行的.Due to many types of resources and high mobility in an Unmanned Aerial Vehicle （U.A.V） network, the traditional access control mechanism cannot achieve the flexible permission management when the authorization changes and the task transfers among UAVs. Therefore, an access control model based on state transition is proposed. The state transition rules are determined by the access properties of object resources, thereby achieving the flexible permission management and subject priority when the authorization changes and resource permissions transfer. Moreover, the experiments in the UAV network environment demonstrate that the execution time for the proposed scheme almost linearly increases with the growing scale of subjects and objects, and that the scheme is feasible in an actual UAV network with complex access control.
