Vehicle data transmission method, device, storage medium and system

Abstract

The invention discloses a vehicle data transmission method and device, a storage medium and a system, and relates to the technical field of vehicles, the vehicle data transmission method is applied to a vehicle end, and the method comprises the following steps: sending a vehicle identification code and an encrypted symmetric key to a server, the server generates a target signature key according to the vehicle identification code and the encrypted symmetric key and feeds back the target signature key; signing vehicle request data according to the target signature key to obtain vehicle signature data; sending the vehicle signature data to the server, so that the server performs signature verification on the vehicle signature data and feeds back a signature verification result; and determining a corresponding data transmission result according to the signature verification result. An independent signature key is provided for each vehicle, so that the risk of key leakage of all vehicles caused by data leakage of a single vehicle due to the fact that all vehicles share a unified key in a traditional scheme is avoided.
