A Secure Vehicular Communication Protocol Using Synchronization of Chen Chaotic System

In vehicular communication, the announcement protocol is crucial for disseminating safety messages to enhance traffic safety and efficiency. Balancing message reliability with vehicle privacy is challenging. Our protocol, using the Chen chaotic dynamical system, addresses this by achieving reliability, privacy, and accountability. It enables vehicles to broadcast messages without revealing identities, ensuring privacy. Misbehaving vehicles can be identified and isolated, maintaining public safety and accountability. Our research provides comprehensive analysis and simulations, demonstrating the improved performance and feasibility of this approach. The Chen chaotic system offers a promising solution to the challenges of reliability, privacy, and accountability in vehicular communication.
