Abstract:
The paper describes a digital simulation environment to reproduce and test attacks on Controller Area Network (CAN) bus systems. Security researchers repeatedly find vulnerabilities in different software components of networked vehicles. Since investigations on the real system seem too costly, various vehicle functions are to be tested and analysed during attacks with the help of a CAN bus simulator. This simulation environment can also be used to conduct on-site and remote training. For the simulation environment, we use the software Vector CANoe as well as CANUTILS to control and analyse the CAN bus systems. In order to be able to analyse the effects and thus the interrelationships and make them comprehensible, a CAN bus simulator was built in the form of a model car. The connection to the model is realised by means of two ESP32-EVB development boards configured as WLAN CAN gateways and a VN1610 CAN-USB interface. In the model, an AT90CAN128 development board functions as a control unit, which controls the motors and the lighting on the model car. The procedure for setting up a CAN bus simulation environment and using it to analyse and evaluate hacker attacks on automotive bus systems is described. The application possibilities show that the simulation environment can not only be used on-site, but in combination with web conferencing systems for theoretical knowledge transfer with a remote connection for solving practical tasks, it represents the most effective methodology for imparting knowledge in the field of car forensics online. Technological obstacles make it difficult to easily integrate practical tasks on real CAN bus systems into conferencing tools, as this requires a connection to the simulation hardware used. Therefore, this paper also shows how, in addition to the BigBlueButton web conferencing system, the AnyDesk remote maintenance software can be used to establish a remote connection to the control machine. Audio-visual feedback is helpful to clarify the effects of the CAN commands sent. Here, webcams are used to control the model car and a remote connection is used to enter the commands.
