A vehicle-mounted t-box and user mobile phone information interaction security authentication system and method

Abstract

The invention discloses a safety certification system for information interaction between a vehicle-mounted T-Box and a user cellphone, and the system comprises a vehicle, the vehicle-mounted T-Box, a T-Box cloud server, and a mobile terminal. The invention also discloses a safety certification method for information interaction between the vehicle-mounted T-Box and the user cellphone, and the method comprises the following steps: 1, inputting the fingerprint of a user through the mobile terminal, enabling the mobile terminal to generate encryption data through the instruction data and fingerprint data and a downloaded APP, carrying out the random ordering of the encryption data, packaging the encryption data, and transmitting the packaged encryption data to a T-Box server; 2, enabling the T-Box server to search the corresponding vehicle-mounted T-Box according to a VIN code linked with an instruction source account, and then transmitting the information to the corresponding vehicle-mounted T-Box; 3, enabling the corresponding vehicle-mounted T-Box to carry out the authentication of the fingerprint information in the data in a safety mode: switching to a normal mode and carrying out the execution of the instruction if the authentication is successful, or else carrying out no operation.

Description

technical field [0001] The invention relates to the field of vehicle information security, in particular to a technology for protecting the information security of the communication process between the vehicle T-Box and the corresponding mobile phone App, and prevents malicious control behaviors by using the mobile phone App to intrude into the vehicle T-Box through a fingerprint authentication system. Background technique [0002] With the development of science and technology, cars are no longer just a means of transportation. At present, the automobile industry is in the era of scientific and technological innovation, and the Internet of Vehicles technology has emerged in response to the situation. The communication between vehicles makes the connection between people and vehicles closer. Car owners can locate, access and control the car through remote services. In addition, vehicle-to-vehicle communication realizes the sharing of behavior information such as speed, posit...

AI Technical Summary

Problems solved by technology

In the existing vehicle T-Box technology, convenience is basically the core of the design, but information security is ignored, and the operation process lacks a strict information security protection mechanism

Even the T-Box equipment of some car manufacturers grants advanced authority to the control commands of the mobile phone App, which can directly control the vehicle power system, but lacks a relatively safe authentication link, and the information protection is relatively weak, which will directly make the vehicle very easy to be serviced remotely. The network is cracked through the network, thus encountering security threats such as loss, theft, and loss of control
