Communication method and related equipment between vehicle-mounted t-box and cloud server

Abstract

The embodiment of the present invention discloses a communication method between a vehicle-mounted T-BOX and a cloud server and related equipment, wherein, when it is determined that the authentication failure database matches the first device information contained in the first CA certificate, according to the authentication failure time record and the first The preset duration determines the number of authentication failures. When the number of authentication failures is less than the failure times threshold, or when the first device information is not matched, CA authentication is performed according to the first CA certificate. When the number of authentication failures is greater than or equal to the failure times threshold, or the CA authentication fails, add the authentication failure time as the first device information at the current moment to the authentication failure database, and return a handshake failure signal to the vehicle T-BOX. When it is determined that the CA authentication is passed, send a handshake success signal to the vehicle T-BOX, and receive the data report message sent by the vehicle T-BOX after the handshake is successful, so as to process the data report message. Improve the safety certification efficiency of the vehicle T‑BOX.

Description

technical field [0001] The invention relates to the technical field of communication, and in particular, to a communication method and related equipment between a vehicle-mounted T-BOX and a cloud server. Background technique [0002] The car networking system consists of four parts, the host, the vehicle T-BOX, the mobile APP and the background system. The host is mainly used for in-vehicle audio and video entertainment and vehicle information display; the vehicle-mounted T-BOX is mainly used to communicate with the background system / mobile APP to realize the display and control of vehicle information on the mobile APP. When the user sends a control command through the mobile phone APP, the background system will send a monitoring request command to the vehicle-mounted T-BOX. After the vehicle-mounted T-BOX obtains the control command, it sends a control message through the CAN bus and realizes the control of the vehicle. Finally, Feedback the operation results to the user...

AI Technical Summary

Problems solved by technology

In the prior art, when the vehicle-mounted T-BOX is required to report data to the cloud server, the cloud server needs to perform security authentication on the vehicle-mounted T-BOX first, and two-way CA authentication is generally used between the vehicle-mounted T-BOX and the cloud server. Improve the security of data communication; however, two-way CA authentication takes a lot of time, resulting in very low security verification efficiency, therefore, it is urgent to improve the above problems
