Abstract: Due to many types of resources and high mobility in an Unmanned Aerial Vehicle (UAV) 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.

Key words: unmanned aerial vehicle network, state transition, fine-grained access control, flexible permission management
