VEHICLE UNLOCKING AUTHENTICATION METHOD AND APPARATUS

The present invention relates to the technical field of vehicles. Disclosed are a vehicle unlocking authentication method and apparatus based on a terminal device. The method comprises : receiving an authentication request sent by a terminal device, and acquiring a device fingerprint and a first authentication code; searching for a prestored service key corresponding to the device fingerprint, and calculating a second authentication code according to the device fingerprint and the service key; and determining a third authentication code and a fourth authentication code on the basis of the first authentication code, the second authentication code, the device fingerprint and the service key so as to complete unlocking authentication of a vehicle by the terminal device. By means of implementing the embodiments of the present invention, unlocking authentication between a vehicle and a terminal device can be realized by means of data obtained after calculation, thereby improving the security of data transmission during the process of authentication between the vehicle and the terminal device.
