Security authentication information acquisition method and device, vehicle, system and storage medium

Abstract

The embodiment of the invention discloses a safety certification information acquisition method and device, a vehicle, a system and a storage medium, the method is applied to the vehicle, a safety chip is installed on the vehicle, the safety chip is used for storing safety certification information, and the method comprises the following steps: determining whether the safety certification information is stored in the safety chip; if the security authentication information is stored in the security chip, performing security communication based on the security authentication information; and if the security authentication information is not stored in the security chip, acquiring the security authentication information from the Internet of Vehicles cipher machine through the Internet of Vehicles server, and performing security communication based on the security authentication information. According to the embodiment of the invention, secure communication is carried out based on security authentication information in a security chip; if the security certification information is not stored in the security chip, the security certification information can be acquired through the Internet of Vehicles controller, so that the problem of long time consumption in the security certification information acquisition process caused by the influence of network factors is solved, and the security certification information acquisition requirements of different vehicle controllers are met.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a method, device, vehicle, system and storage medium for obtaining security authentication information. Background technique [0002] When intelligent networked vehicles bring users a better driving experience, it is also particularly important to meet the information security requirements of each networked part, such as identity authentication, security trust, information interaction, and data confidentiality. [0003] At present, in order to meet the needs of information security, the controller will be used to apply for the key and certificate online from the encryption machine of the car factory through the network, and then the applied key and certificate will be preset in the controller to meet the requirements of each network connection part. The purpose of information security requirements such as identity authentication, security trust and so on. ...

AI Technical Summary

Problems solved by technology

[0004] If the controller applies for keys and certificates online, it will be affected by factors such as poor network stability or slow network speed, which will take a long time to apply for keys and certificates.
