A study on recent applications of blockchain technology in vehicular adhoc network (VANET)

Abstract

Technology has taken over aspects of our lives today, which were unimaginable a few years ago. Innovations such as high-end transport systems that include connected autonomous vehicles (CAV), and digital currencies, such as Bitcoin and Ethereum, have made our lives more comfortable and convenient. It may not seem at first, but most of these technologies work on similar lines. For example, CAVs use DSRC (Dedicated Short-Range Communication) technology, which has a peer-to-peer aspect. On the other hand, Bitcoin uses a technology called Blockchain, which was founded on its peer-to-peer nature and lack of need for a trusted central authority. Cybersecurity of vehicular ad hoc network (VANET) has become a prime research area for cybersecurity researchers. Minor vulnerabilities in VANET may lead to severe fatalities. This concernment has engaged numerous researchers with the purpose of improving the defense mechanism of these susceptible networks. This paper presents a brief meta-analysis of the field of cybersecurity of autonomous vehicles using Blockchain and discusses how VANETs and CAVs can be protected using the same.
