Abstract

VANETs are crucial for ITS, but their wireless nature poses security risks. Blockchain offers secure authentication and privacy. This chapter proposes a BC-based security system with a TMS using RSUs and CAs. The system identifies malicious nodes and forged messages using reputation and message metrics. A modified XGBoost and decision tree model calculate trust based on role, distance, and direct trust assessment. Experiments show BC-TMS is efficient, resilient, and ensures VANET security. Compared to existing centric trust models, the proposed paradigm is straightforward, trustworthy, and effective. In order to test BC-TMS in terms of safety, correctness, and reliability, a series of experiments are carried out, and the findings demonstrate that BC-TMS is not only efficient but also highly resilient, thereby establishing a trust model for VANETs that ensures the utmost security and protection.
