In this work, we evaluate the safety of a platoon offour vehicles under jamming attacks. The platooning applicationis provided by Plexe-veins, which is a cooperative drivingframework, and the vehicles in the platoon are equipped withcooperative adaptive cruise control controllers to represent thevehicles’ behavior. The jamming attacks investigated are modeledby extending ComFASE (a Communication Fault and AttackSimulation Engine) and represent three real-world attacks,namely, destructive interference, barrage jamming, and deceptivejamming. The attacks are injected in the physical layer of theIEEE 802.11p communication protocol simulated in Veins (avehicular network simulator). To evaluate the safety implicationsof the injected attacks, the experimental results are classifiedby using the deceleration profiles and collision incidents of thevehicles. The results of our experiments show that jammingattacks on the communication can jeopardize vehicle safety,causing emergency braking and collision incidents. Moreover,we describe the impact of different attack injection parameters(such as, attack start time, attack duration and attack value) onthe behavior of the vehicles subjected to the attacks.
