EIoVChain: Towards Authentication and Secure Communication Based Blockchain for Internet of Vehicles (IoV)

As the backbone of smart cities, the IoV has the potential to greatly enhance transportation effectiveness, passenger and driver safety, reduction of energy use, and road accidents. However, due to the fact that the vehicle, Road-Side-Units (RSU), and Edge Server use wireless channels to communicate, the risk of leaking or falsifying information is greatly improved. We offer EIoVChain, a reliable registration and authentication, secure information sharing based on the IoV edge server blockchain schema with minimal latency and efficient storage to address these issues. EIoVChain works with a novel primary node allocation algorithm that selects primary nodes based on their decentralized trust and a block verification process that identifies the transaction's validity of that block. The consensus algorithm follows the practical Byzantine fault tolerance model (PBFT) which works even when opposing nodes are active in EIoVChain. We have implemented EIoVChain on Raspberry pi 4. Experimental results show that EIoVChain outperforms conventional solutions with 66% verification delay and 49% communication overhead.
