Abstract
The Internet of Vehicles (IoV) integrates wireless, mobile networking, cloud infrastructure, IoT, and wireless sensor networks, establishing an intelligent transportation system. While electric vehicles (EVs) contribute to environmental sustainability, they encounter challenges; battery-swapping technology emerges as a viable solution. Nevertheless, concerns arise regarding data security, privacy, and potential single points of failure. To address these issues, we propose a privacy-preserving authentication protocol based on intelligent blockchain. This protocol ensures the security and reliability of data storage and transaction verification processes, simultaneously upholding privacy, including user anonymity and untraceability. Additionally, leveraging the decentralized nature of intelligent blockchain, each participating node retains a copy of the data and verifies it through consensus algorithms to ensure its integrity and credibility. Verification using the Real-Oracle Random (ROR) model demonstrates both effectiveness and security, with informal analysis confirming resilience against known attacks. Comparative analysis underscores the proposed protocol’s security and performance advantages, placing emphasis on its reliability.
