Message
Falsification: In this attack, the adversary listens to wireless
communication medium between the vehicles in a platoon and, upon
receiving each beacon, manipulates the content meaningfully and
rebroadcasts it.
Spoofing:
In this attack, the adversary impersonates another vehicle in the stream in order to inject fraudulent information into a specific vehicle. This attack can result in a crash.
Replay Attack: In this attack, the adversary
receives a legitimate beacon from a vehicle in a platoon and stores it.
It then replays it later with a malicious intent. For example, an
adversary may store a broadcast that says a given vehicle is travelling
70 mph. It may rebroadcast it later to another vehicle in the platoon
causing an accident.
Collision Induction Attack: In this
attack, the adversary broadcasts an incorrect speed to the other
vehicles in a platoon resulting in a crash. For example, an adversary
decelerating to 80km/hr might broadcast a speed of 200 km/hr causing
the following vehicles to speed up and crash into each other.
Leader
Crash Attack: In this attack the adversary of a platoon will crash
resulting in the following vehicles to crash. The vehicles following
the leader will not have the time or the space to stop safely and
hence, will crash into the leader.
Denial of Service (DoS): In this attack, the adversary can overwhelm the communication capability of a vehicle by sending numerous amounts of messages, resulting in the loss of communication and a temporary disbandment of the platoon.
Radio
Jamming: In this attack, the adversary can jam the area near vehicles and hence preventing any communication between them. This can either result in a dissolved platoon or a crash.
