In Cooperative Intelligent Transport Systems (C-ITS), vehicles exchange messages to improve road safety, traffic flow, reduce CO₂ emissions, and support automated vehicles. Platooning, a cooperative driving application, allows vehicles to share position, speed, acceleration, etc., to maintain minimal safe distances and coordinate maneuvers. Cooperation depends on reliable information; existing C-ITS protocols ensure sender authenticity but not data correctness, allowing faulty or malicious data to propagate. This thesis addresses the challenge of ensuring reliable communications for cooperative driving applications by proposing a secure and trusted framework, combining a dedicated communication protocol with integrated misbehavior detection mechanisms. Vehicles assess data reliability and sender trustworthiness, adapting their behavior to maintain safe coordination. Simulations with PLEXE and SUMO validate the effectiveness of the proposed solutions.
