Elliptic curve encryption-based unmanned aerial vehicle and base station communication identity authentication method

Abstract

The invention aims to design an elliptic curve encryption-based unmanned aerial vehicle and base station communication identity authentication method, which comprises the following steps that: in an initialization stage of a system, a trusted center generates system parameters and broadcasts the system parameters to an unmanned aerial vehicle network; each unmanned aerial vehicle in the unmanned aerial vehicle group is authenticated and registered by the trusted center; the pavement base station and the unmanned aerial vehicle initiate an authentication request; and after successful authentication, the pavement base station sends an instruction packet to the unmanned aerial vehicle, and the unmanned aerial vehicle receives the instruction and executes an instruction task. The authentication method is mainly based on the elliptic curve cryptography theory, and based on the elliptic curve discrete logarithm problem (ECDLP), it is guaranteed that communication data are difficult to crack;the flow of identity authentication between the unmanned aerial vehicle and the pavement base station effectively protects the communication security of the pavement base station and the unmanned aerial vehicle, ensures the identity privacy of the pavement base station and the unmanned aerial vehicle, can effectively prevent replay attacks and man-in-the-middle attacks, prevents the unmanned aerial vehicle from executing malicious tasks due to malicious attacks, and ensures the communication security of the unmanned aerial vehicle.

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...
