Detection and Mitigation of Data Tampering Attacks for Cooperative ACC Systems Based on C-V2X.

Cooperative adaptive cruise control (CACC) systems allow vehicles to drive in platoon formations using wireless communication. However, CACC systems are exposed to network-induced cyberattacks, such as data tampering attacks, using fake base stations. This study proposes a detection and mitigation method for data tampering attacks on CACC systems based on cellular vehicle-to-everything (C-V2X) communication. Simulations confirm that a system using the proposed method can detect and mitigate data tampering attacks by using redundant C-V2X communication paths.
