Automobile bus network design security detection method

Abstract

The invention belongs to the technical field of vehicle-mounted network detection, and particularly relates to an automobile bus network design security detection method, which comprises the following steps: a message acquisition step: acquiring message information of a whole automobile, the content of the message information comprising a message identifier and corresponding data segments; a message processing step: processing the message information, keeping the message identifier unchanged, processing the corresponding data segments according to a preset processing flow to obtain a plurality of attack messages, and sequentially sending the attack messages to a vehicle-mounted network; and a protection evaluation step: recording a safety protection result of the vehicle-mounted network according to the response of the whole vehicle to the attack messages. The method can comprehensively and accurately detect the protection capability of the vehicle-mounted network to external attacks.

Description

technical field [0001] The invention belongs to the technical field of vehicle network detection, and in particular relates to a safety detection method for vehicle bus network design. Background technique [0002] With the rapid development of intelligent networked vehicles, the controllers in the vehicle can realize the functions of the whole vehicle through signal interaction through the vehicle network. The security of the vehicle network is very important to driving safety. If there are network attacks such as vehicle data tampering and node counterfeiting, it will pose a threat to the safety of people in the vehicle. Therefore, it is necessary to test the protection capability of the vehicle network. [0003] However, in the prior art, when testing the security protection capability of the vehicle-mounted network, the technical idea is still to use the simulated attack idea of ​​the Internet, such as through data replay, reverse or data flooding, to understand the sec...

Problems solved by technology

[0003] However, in the existing technology, when testing the security protection capability of the vehicle network, the technical idea is still the simulated attack idea of ​​the Internet, such as through data replay, reverse or data flooding, to understand the security protection capability of the vehicle network

Although such a test method is highly versatile, it also has the following problems: First, the comprehensiveness of the test is insufficient. The communication matrix of the vehicle network covers a lot of functions, and the core of the Internet test method is indiscriminate data attack. , and it is aimed at network security rather than functional safety, and will not test individual functions in turn, and cannot detect all functions of the vehicle network; second, the test is not targeted enough, due to the particularity of the signal design method of the vehicle network communication matrix , to know whether a function in a certain state (such as power-on, start-up, acceleration, etc.) Definitions are processed, so targeted detection of a single function cannot be achieved
