Abstract: The present disclosure relates to a method of operating an electronic device that provides a key agreement protocol. Specifically, the method may include obtaining at least one of an ID of a user, a first anonymous ID of the user corresponding to the ID of the user and a first temporary authentication value of the user, from a user terminal, obtaining at least one of an ID of an unmanned aerial vehicle (UAV), a first anonymous ID of the UAV corresponding to the ID of the UAV and a first temporary authentication value of the UAV, from the UAV, and in response to a key agreement request of the user terminal or a key agreement request of the UAV, intermediating key agreement between the UAV and the user terminal based on first information including information obtained from the user terminal and second information including information obtained from the UAV.

Abstract: Provided is an electronic device, including a database and a processor, and the processor is configured to receive a user ID, at least one anonymous user ID corresponding to the user ID and location information of a user terminal from the user terminal, receive an unmanned aerial vehicle (UAV) ID, at least one anonymous UAV ID corresponding to the UAV ID and location information of an UAV from the UAV, and in response to receiving key exchange request information from the user terminal or the UAV, provide a key exchange protocol between the user terminal and the UAV based on the location information of the user terminal and the location information of the UAV.
