An identity authentication method for UAV and base station communication based on elliptic curve encryption

Abstract

The purpose of the present invention is to design a UAV and base station communication identity authentication method based on elliptic curve encryption, including: the system is initialized, the trusted center generates system parameters and broadcasts them to the UAV network; Each drone is authenticated and registered by the trusted center; the road base station and the drone initiate an authentication request; after the authentication is successful, the road base station sends an instruction packet to the drone, and the drone receives the instruction and executes the instruction task. The authentication method is mainly based on the theory of elliptic curve cryptography, based on the Elliptic Curve Discrete Logarithm Problem (ECDLP) to ensure the difficulty of deciphering the communication data; The communication security of the drone ensures the identity privacy of the road base station and the drone, and can effectively prevent replay attacks, man-in-the-middle attacks, prevent malicious attacks from causing the drone to perform malicious tasks, and ensure the communication security of the drone.

Description

technical field [0001] The invention belongs to the technical field of encrypted communication, and in particular relates to an identity authentication method for communication between a drone and a base station based on elliptic curve encryption. Background technique [0002] With the development of UAV technology, the potential risks and security problems of UAVs have gradually become prominent, and UAVs are also more vulnerable to malicious attacks. Threats to drone safety may come from flight controllers and ground controllers, wireless data links, sensor road infrastructure. Since the UAV communicates through the wireless network, the attack is generally carried out through the wireless channel. During the data communication of the UAV, it will also cause man-in-the-middle attacks, replay attacks, and denial-of-service attacks. At present, most drones do not consider malicious attacks when communicating, so no authentication is required during the data transmission pro...
