Abstract

The embodiment of the invention discloses an identity authentication method and device and a medium. The method is applied to a vehicle of a system composed of a server, a terminal and the vehicle, and comprises the following steps: receiving a digital key sent by the terminal, wherein the digital key comprises vehicle end information and terminal identity information; calculating harsh values ofthe vehicle end information and the terminal identity information; and if the harsh value is in a white list, outputting allowable control information. The problem that the identity authentication method in the prior art is relatively low in security is solved, and a technical effect of effectively protecting user information is achieved.

Description

technical field [0001] The embodiments of the present invention relate to the field of vehicle control, in particular to an identity authentication method, device and medium. Background technique [0002] With the rapid development of science and technology, technologies such as car sharing and driverless driving have brought great convenience to our lives. However, technologies such as car sharing and driverless driving are all based on the Internet of Vehicles. While intelligence brings us convenience, it also faces system security issues brought about by smart cars. The Internet of Vehicles takes "two ends and one cloud" as the main body, supplemented by roadbed facilities, including intelligent networked vehicles, mobile smart terminals, and Internet of Vehicles service platforms, etc., involving vehicle-cloud communication, vehicle-vehicle communication, vehicle-human communication, In the five communication scenarios of vehicle-road communication and in-vehicle commun...
