The Internet of Vehicles (IoV) can greatly increase the effectiveness of transportation systems and guarantee traffic safety. A fundamental line of defense against attacks in IoV is authentication. However, cutting-edge methods have several problems, such as leakage of vehicle trajectory confidentially, bottlenecks of a single cloud server architecture, significant computing overhead of operations, and an excessive reliance on cloud servers and roadside units (RSUs). To solve these issues, BEPHAP, an effective privacy-preserving handover authentication mechanism based on blockchains, as well as the Internet of Vehicles' flagship protocol, are presented in this study. With key protocols based on tamper-proof blockchains, symmetric cryptography, and chameleon hash functions and a security paradigm that supports cloud server and RSU assaults, BEPHAP achieves anonymous cross-domain mutual handover authentication. BEPHAP is especially well suited for IoV since it restricts vehicle activity to minimal cryptographic operations during the authentication stage. Data confidentiality, unlinkability, traceability, non-repudiation, non-frame capability, and key escrow freedom are also attained by BEPHAP. Formal security proofs based on BAN logic and formal verification based on ProVerif show that BEPHAP is resistant to a variety of targeted assaults, including man-in-the-middle, impersonation, and replay attacks. According to the performance analysis, BEPHAP performs better than other functions in terms of computing and communication. At 5000 requests per second, the message rate is not lost, which satisfies the IoV criteria.
