Impacts of Security Attacks on The Effectiveness of Collaborative Adaptive Cruise Control Mechanism

Connected vehicles are equipped with devices that enable them to communicate with external entities, such as other vehicles. This capability is currently used to implement Cooperative Adaptive Cruise Control (CACC). This paper discusses the impact of security attacks on safety of using CACC. It reports about simulating the impact of four security attacks on the effectiveness of CACC in the context of a merging scenario of an abstract system. The simulation showed that attacks on the communication between the vehicles cause collisions with non-negligible proportion. The results suggest the need for strong security assurance for CACC applications.
