Security Analysis of LTE-V2X and A Platooning Case Study

C-V2X extended from cellular networks has been considered one of the promising communication techniques for Internet of Vehicles (IoV). Correspondingly, it inherits the security issues from cellular networks, i.e., LTE or 5G, and also bring new types of security issues. In this paper, we take LTE-V2X as an example to investigate the potential security and privacy issues of LTE-V2X. In particular, we first study the LTE-V2X communication procedure and discover the potential security flaws. Then we use the platooning case to show the harmfulness caused by different types of attacks using the security flaws. Finally, we use SUMO and OMNET++ to simulate platoon and LTE-V2X, and conduct different types of attacks on the simulator. The simulation results show that various attacks severely degrade the performance of platoon from the perspective of inter-vehicle distance and vehicle speed.
