This research focuses on addressing the critical issue of Sybil attacks in Vehicular Ad-hoc Networks (VANETs), which pose serious threats to the security and reliability of communication among vehicles and Roadside Units (RSUs). The proposed solution introduces innovative protocols leveraging concepts from the Secure Electronic Transactions (SET) protocol and Blockchain technology. Notably, the research introduces a novel concept, "Proof of Trajectory (PoTr)," enhancing vehicle authentication and countering identity spoofing—the primary technique employed by Sybil attackers. The study includes implementation details, simulation experiments, and evaluation results demonstrating the effectiveness of the proposed protocols in detecting and preventing various types of attacks, including Identity Spoofing, Man-in-the-Middle, and Replay attacks. The outcomes present VSCI as a robust and secure communication framework for VANETs, contributing to the advancement of security solutions in the context of dynamic and mobile ad-hoc networks.
