ABSTRACT
The Internet of Vehicles (IoV) is an emerging technology that allows the interconnection of smart vehicles with each other via the Internet. Smart vehicles share data to improve driving safety and efficiency. However, shared messages can face several security and privacy issues. Therefore, ensuring security and privacy in IoV is highly required. In this work, we present up-to-date blockchain-based solutions to secure IoV applications. A comprehensive comparison of classical and blockchain-based security schemes for IoV is provided. Moreover, we discuss open issues related to the integration of blockchain technology in IoV and propose an efficient architecture to address the delay and scalability issues.
