A Review of Blockchain Based Approach for Secured Communication in Internet of Vehicle (IoV) Scenario

Technology advances through time and fast development accompanies over the time. Telecommunications and wireless technology are pioneers among the emerging technologies. Vehicular Ad-hoc Network is the most progressive and foreseen research field under wireless communications as they are able to provide a large variety of ubiquitous services. They are a growing technology which provides a vast range of safety applications for the vehicle passengers. With an increase in such services, there will be an increase in the vulnerabilities which could be compromise the VANET communication. Successfully defending against such VANET’s attacks is continuously under research and growth. Blockchain offers decentralized, distributed, collective maintenance to counter malicious attacks. In view of the aforesaid issues, in this paper a dedicated discussion of various research works related to privacy and authentication schemes in VANETS using Blockchain has been made.
