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.
