T-BOX information security detection and protection method based on vehicle anomaly data monitoring

Abstract

A T-BOX information security detection and protection method based on vehicle anomaly data monitoring comprises: classifying and summarizing vehicle faults, providing a universal vehicle fault tree model, collecting and comparing vehicle real-time data through T-BOX, monitoring vehicle anomaly data in real time, transmitting to a telematics service platform (TSP) constantly, determining change trends of operation parameters and states of each vehicle part and system through data fusion and through big data analysis based on vehicle driving historical information collected by a cloud terminal and vehicle main parts related information restored by a main engine plant, comparing vehicle real-time information transmitted by T-BOX, judging whether a vehicle has anomaly data or not at present, and determining whether the vehicle is under information security attack or not based on the established vehicle fault tree model; finally, notifications or warnings on fault problems due to vehicle functional security need to be made for users and vehicles by the TSP.

Description

Technical field [0001] The invention relates to the technical field of automobile information security, and is suitable for vehicle information security protection, in particular to a T-BOX information security detection and protection method based on vehicle abnormal data monitoring. Background technique [0002] With the vigorous development of automobile intelligence, networking, and informatization, the market share of intelligent networked vehicles is increasing. At the same time, information security issues brought about by complex in-vehicle networks, on-vehicle sensors, wireless communication networks, and remote information service systems have gradually attracted people’s attention. The relevant state departments, industries and industries are even more concerned about the information security of connected vehicles. The problem is placed first in the industry's key technology research. [0003] Existing automotive information security products mainly include on-board gat...

Problems solved by technology

[0006] At present, most T-BOX products on the market only have simple network conversion and data transmission functions, but do not have information security detection and protection capabilities. Functionally, they are only network protocol converters, and information security detection and protection are mainly through the cloud. The server implements

However, the entire information security protection system of intelligent networked vehicles relies entirely on the cloud, and there will be many problems. For example, the vehicle itself does not have information security protection capabilities, and it is threatened or attacked in the cloud (such as the firewall is breached, the server is invaded), and the vehicle is physically attacked. In this case, the vehicle will lose its ability to protect information

In addition, the information security protection mode based on the cloud is vulnerable to interception of communication information by attackers, resulting in the loss and theft of vehicle information, resulting in user privacy exposure and economic losses, and even serious consequences of vehicle crashes.
