Abstract

The embodiment of the invention provides a vehicle attack detection method and device. The method specifically comprises the steps of collecting car body bus data; determining information entropy corresponding to the car body bus data; if the information entropy exceeds a preset range, determining that a car body bus is attacked, and sending a warning message. According to the vehicle attack detection method and device, whether the car body bus is attacked or not can be detected, when it is determined that the car body bus is attacked, the warning message can be sent, so that a user takes measures to stop deep development of the attack as soon as possible, and the traffic safety and information safety of the user are accordingly improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a vehicle attack detection method and device. Background technique [0002] With the continuous development of network technology, vehicles can pass through 3G (3rd-Generation, third-generation mobile communication technology) / 4G (the 4th Generation mobile communication technology, fourth-generation mobile communication technology), Wi-Fi (WIreless-Fidelity, Wireless Fidelity) and other ways to access the Internet, download resources such as videos and music from the Internet, or, it can also realize remote control of vehicles through the Internet, which brings great convenience to users. [0003] While the Internet brings convenience to users, the issue of vehicle information security has become particularly important. More and more vehicle local area networks adopt Internet standards, and it becomes easy to break through the "firewall" inside the vehicle. For vehicles co...
