BEIT: Blockchain-Enabled Internet of Vehicles Trust with Vehicle Authentication Handover

Technological developments in the communications sector are augmenting the Internet of Vehicles (IoV) to a great extent. As a result, the IoV environment is changing and includes lower costs, lightning-fast data exchange, and minimal response time. However, when cyberspace grows, these advantages come with increased privacy and security problems. IoV causes communication hiccups and network congestion as vehicles rely on trusted authorities (TA) for registration and authenticity. Furthermore, the traceability, anonymity, and transparency of the intermediary devices and the central TA need to be made clear. This paper uses blockchain technology to propose a unique vehicle authentication handover framework to overcome these issues. The suggested solution also integrates Proof of Reputation (PoR), an updated blockchain consensus algorithm, to improve transparency. Using the Elliptic Curve Cryptography (ECC) to minimise computational delay time, the method reduces key sizes without affecting security.
