Impact of Security Attacks on Cooperative Driving Use Case: CACC Platooning

The next big innovation in the automotive industry is connected and automated vehicles (CAVs). CAVs would allow a higher throughput in the roads and also lead to fewer accidents. Currently, Level 4 autonomy has been achieved in the labs, and active research is being done to achieve full autonomy (Level 5). To improve road safety, traffic and many other driving scenarios, communication between vehicles and infrastructure are key. However, connectivity between Autonomous vehicles also opens doors for cyber-attacks. In this study, we use VENTOS, a simulation platform based on SUMO and OMNET++ to model various attack on the cooperative driving use case cooperative adaptive cruise control based platooning and show their impacts. Our simulation-based study shows that various attacks exploiting the communication between vehicles can cause significant problems related to safety and stability in the platoon.
