The UAV management system is a system that reviews and approves the scheduled flight time, traffic conditions and route safety before the UAV is flying. Through this system, only approved aircraft must be able to make scheduled flights to prevent accidents and abuse by UAVs. In addition, the UAV service provider receives prior authorization through this management system and controls the UAV according to the set time and route. In this paper, by designing the UAV arming authorization using DIM and flight authentication code, we provide a method to prevent the UAV service provider's mistake from flying in the unauthorized time and route of another identification code.
