Abstract

The invention provides an automobile CAN bus information security testing method, which identifies the automobile CAN bus pins; identifies the automobile CAN bus baud rate; reads the automobile CAN bus data; generates the automobile CAN bus safety test data, analyzes the CAN bus data, and aims at Each channel of CAN bus data produces a specific test data package; sends CAN bus safety data, observes the state of the car, and determines whether the car has safety problems; analyzes the vulnerabilities obtained by the test, outputs the vulnerability analysis report, and gives repair suggestions. The invention has the beneficial effects that the bus bidirectional data transmission can be realized, the bus fault can be monitored in real time, and the bus can be guaranteed not to lose frames and the bus data can be received stably; The information security test of CAN bus provides a good guide.

Description

Technical field [0001] The invention belongs to the field of automobile safety, in particular, involving a safety test method of automobile CAN bus information. Background technique [0002] With the rapid development of intelligent networks, automotive information security issues are increasingly high. How to effectively avoid automotive information security issues, need to strengthen information security testing of automobiles, timely discovery of security issues, and repair. However, for the security of the intelligent network of automobile CAN bus information, no mature automotive information safety test methods, test tools and test systems are not formed. Inventive content [0003] In view of this, the present invention aims to present a car CAN bus information security test method to address the shortcomings of the above problems. [0004] In order to achieve the above object, the technical solution of the present invention is achieved: [0005] A car CAN bus information s...
