The intelligent vehicles collect and distribute the data to other vehicles and Roadside Units (RSU), which ultimately strengthens the vehicular services in the Vehicular Ad-hoc Network (VANET). In order to protect against a variety of potential security threats, the VANET system needs a proper authentication mechanism, which requires more computational overheads and cannot perform better, when a cluster of vehicles sends the messages simultaneously. This paper aims to design a decentralized blockchain-based batch authentication protocol using Elliptic Curve Cryptography, where RSU authenticates the group of vehicles together. Moreover. our protocol also supports the verification of both individual messages (signature) generated by the vehicle and batch signature. We have used the Scyther security tool to verify our protocol and found that the protocol is safe and secure. A detailed comparative analysis reveals that the proposed scheme achieves more functionality and security compared to relevant schemes. The security analysis confirms that the proposed scheme is secure against all applicable attacks. Moreover, the ethereum platform simulates the proposed scheme, showing its effectiveness and confirming that it is feasible to deploy and execute transactions in real networks.
