SIoVChain: Efficient and Secure Blockchain Based Internet of Vehicles (IoV)

As the backbone of smart cities, the IoV can greatly enhance transportation effectiveness, passenger and driver safety, energy use reduction, traffic management, and pollution control. Although, the storage and communication between ubiquitous devices such as the vehicle and Road-Side-Unit (RSU) lead to multiple potential challenges, such as data tampering, data integrity, cyber attacks, and risk of leaking or falsifying information. In this work, we have proposed a permissioned blockchain framework for the IoV (i.e., SIoVChain) to overcome insecure data communication and inefficient data storage. SIoVChain registers ubiquitous devices with a node such as a blockchain node and works with transaction verification and ordering node selection processes. SIoVChain directly benefits the drivers and passengers by providing traffic information through secure communication and data integrity. We have implemented SIoVChain on the Raspberry Pi 4 platform. The experimental results demonstrate that SIoVChain surpasses conventional solutions by 50% verification delay, 50% cryptography latency, and 49% communication overhead.
