Vehicle CAN bus simulation and attack system and method

Abstract

The invention discloses a vehicle CAN bus simulation and attack system and method. The system comprises a CAN node simulating an ECU, a PC terminal and OBD-II; the CAN node is connected to a bread board of the CAN node through two interfaces of a CAN-H bus and a CAN-L bus, and is connected to a multi-port USB interface board through a serial port, and the multi-port USB interface board is connected to a PC end to complete serial port communication between the CAN node and the PC; the OBD-II is connected to the CAN-H and the CAN-L of the serial CAN node through two CAN bus connecting lines. According to the method provided by the invention, a vehicle ECU is simulated mainly through Ardunio; operation of a vehicle CAN bus is simulated through serial port communication with the PC and importing of vehicle CAN real data, and meanwhile the system carries out various attacks including a hang-up attack, a pretending attack, a camouflage attack and the like on the CAN bus and an ECU of a simulation vehicle.

Description

technical field [0001] The invention belongs to the field of industrial internet of things security, and relates to a vehicle CAN bus simulation and attack system and method. Background technique [0002] With the accelerated integration of Internet of Things technology and the automobile industry, the degree of intelligence and networking of modern vehicles continues to deepen. In order to provide users with a more comfortable driving experience, the number of automotive electronic control units (Electronic Control Unit, ECU) has increased year by year, and the communication interface with the outside world, such as 3G / 4G, Bluetooth, etc., has become more abundant, and the vehicle is no longer an isolated and closed system. Not a mechanical product, but an open system with a complex in-vehicle network. The openness and electronicization of vehicles have led to increasingly prominent network security issues. Once hackers enter the vehicle network through external interfaces...
