Radio Jamming in Vehicle-to-Everything Communication Systems: Threats and Countermeasures

More than 1.35 million lives are lost due to traffic accidents, with 94% of these accidents caused by human error. In order to significantly improve the traffic safety and efficiency, automated driving systems, including Advanced Driver Assistance Systems (ADAS) and autonomous driving, exchanges sensor and perception data between the automated vehicle and its surrounding objects via Vehicle to Everything (V2X) communication. Although V2X technologies, such as dedicated short-range communication (DSRC) and cellular vehicle-to-everything (C-V2X), are essential for the safety in certain driving use cases, they may completely fail in the presence of radio interference. Therefore, the development of robust V2X systems to deal with radio jamming in automated driving applications is crucial. In this paper, we present scenarios of the radio jamming attacks considering traditional driving use cases of V2X systems and we propose countermeasures against these attacks. Using a simulation environment, we validate the proposed countermeasures mitigating the effects of radio jamming.
