The Amalgamation of Blockchain with Smart and Connected Vehicles: Requirements, Attacks, and Possible Solution

Abstract

Smart and connected vehicles play a vital role in today's advanced and luxurious life. Vehicular Ad-hoc Network (VANET) allows communication between these vehicles regarding safety and control messages, road situations, and surrounding environments. VANET demands security requirements like authentication, availability, confidentiality, reliability, etc. These requirements have crucial attacks associated with it which hampers a system to work. Blockchain is an immutable, distributed, decentralized, smart contract-based technology that provides an efficient solution to VANET requirements and their corresponding attacks. This paper discusses various such requirements and attacks and their possible solutions with Blockchain. Apart from that, Blockchain also acts as a prominent solution to deal with the challenges being faced by electric and autonomous vehicles to come to reality. We have reviewed, analyzed, and discussed the proficient researcher's works and their contributions in this paper to unfold new directions in the present and future research. Further, we have analyzed and discussed the insurance, and forensic management is amalgamated with Blockchain by various researchers to create an automatic assessment protocol. Future possibilities for smart and connected vehicles with Blockchain could be a major objective of this paper.
