Abstract
As V2X system has developed, some vehicles that are recently released have been designed to meet the requirements of cooperative automated driving technology. Cooperative automated driving is the method of communication between the car and the surrounding infrastructure, and it predicts the surrounding situation through the V2X communication system to prevent unexpected accidents and situations that external sensors of the car are not aware of. In this environment, external security threats are also possible through each contact points while V2X (Vehicle to Everything) system communicates with Ethernet-based WAVE (Wireless Access in Vehicle Environment) through antenna, GPS module, and OBU (On Board Unit). Those all can generate false messages, for example, which are modulating location data by disturbing the GPS, manipulating the WAVE messages inside the OBU, or injecting internal CAN messages to cause propagation of wrong situation. Based on these potential threats, this paper presents possible cyber-attack scenarios in V2X environment.
