BCoV: a covergence of blockchain and IoV

Abstract

The information generated by the internet of vehicles during normal operation involves personal privacy. Due to the lack of appropriate information security mechanisms in IoV architecture, IoV has the risk of privacy leakage. However, the emergence of blockchain brings opportunities to solve these problems. The combination of blockchain and IoV can make full use of the advantages of the blockchain (such as distributed storage, and smart contracts) to solve some problems in the IoV. In this paper, we investigate the combination of blockchain and IoV and name this structure as BCoV. Firstly, we introduce the structure of IoV and discuss the challenges of IoV. Secondly, we outline the blockchain structure, consensus algorithm, and smart contract. Thirdly, we discuss the convergence of blockchain and IoV and propose the architecture of BCoV, and make a comparison with IoV. Fourthly, we introduce some applications of BCoV. Finally, we present the challenges of BCoV.
