Communication method for vehicle-mounted T-BOX and cloud server and related equipment

Abstract

The embodiment of the invention discloses a communication method for a vehicle-mounted T-BOX and a cloud server and related equipment, and the method comprises the steps: determining the number of authentication failures according to an authentication failure time record and a first preset duration when determining that an authentication failure database matches first equipment information contained in a first CA certificate; and performing CA authentication according to the first CA certificate when the authentication failure frequency is smaller than the failure frequency threshold or the first equipment information is not matched; when the authentication failure frequency is greater than or equal to a failure frequency threshold or CA authentication is not passed, adding the current moment as authentication failure time of the first equipment information into an authentication failure database, and returning a handshake failure signal to the vehicle-mounted T-BOX; and when it is determined that CA authentication is passed, sending a handshake success signal to the vehicle-mounted T-BOX, and receiving a data report message sent by the vehicle-mounted T-BOX after handshake is successful, so as to process the data report message. The security authentication efficiency of the vehicle-mounted T-BOX is improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a communication method between a vehicle-mounted T-BOX and a cloud server and related equipment. Background technique [0002] The car networking system consists of four parts, the host, the car T-BOX, the mobile phone APP and the background system. The host is mainly used for audio-visual entertainment in the car and vehicle information display; the vehicle T-BOX is mainly used for communication with the background system / mobile APP to realize the vehicle information display and control of the mobile APP. When the user sends a control command through the APP on the mobile phone, the background system will send a monitoring request command to the vehicle T-BOX. After the vehicle T-BOX obtains the control command, it will send a control message through the CAN bus and realize the control of the vehicle. Feedback the operation results to the user's mobile APP. Only this fun...

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
