CAN bus risk detection method and device

Abstract

The present invention provides a CAN bus risk detection method and device. The method is applied to a device connected with the CAN bus interface of a target vehicle and includes the following steps that: the vehicle model information of the target vehicle inputted by a user is received, and a private protocol corresponding to the vehicle model inputted by the user is searched in the private protocols of various pre-stored vehicle models; a task creation request inputted by the user is received, a new detection task is created according to the private protocol corresponding to the vehicle model inputted by the user, a detection type carried by the task creation request, and a detection target; and a data frame is constructed based on the detection task when a command for initiating the detection task is received, and the constructed data frame is sent to the CAN bus system of the target vehicle through the CAN bus interface of the target vehicle; response information returned by the CAN bus system of the target vehicle is received, and a detection report is generated according to the response information and is outputted. With the CAN bus risk detection method and device of the present invention adopted, a safety risk in the CAN bus system of the vehicle is detected.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a controller area network (Controller Area Network, CAN) bus risk detection method and device. Background technique [0002] In recent years, hackers at home and abroad have successfully cracked a variety of car models through wireless and wired intrusions. The attacker can control the vehicle system or electronic control unit by invading 3G / 4G, Wi-Fi, Bluetooth, radio frequency and other wireless networks, and can also invade the vehicle's CAN bus system through the vehicle's CAN bus access. [0003] Whether it is a wired or wireless attack, it is through reading and writing frame data on the CAN bus to obtain vehicle information, realize remote control of the vehicle, and even destroy the availability of the vehicle, seriously threatening the safety of the owner's life and property. Contents of the invention [0004] In view of this, the purpose of the present i...
