Abstract

The increasing popularity and deployment of Internet of Vehicles (IoV) along with Connected Autonomous Vehicles (CAVs) have benefits ranging from enhanced road safety to efficient traffic management. However, with the increasing connectivity and data exchange among vehicles, the security of IoV systems becomes paramount. In this project, I have proposed a novel approach for ensuring secure access control within IoV environments using the Proof of Elapsed Time (PoET) consensus mechanism of Blockchain. As a lightweight consensus algorithm based on trusted execution environments (TEE), PoET offers a robust solution for securely managing access permissions in dynamic IoV scenarios. A detailed analysis of the proposed system architecture, highlighting its resilience against various security threats including unauthorized access, data tampering, and Sybil attacks, has also been discussed. Additionally, the implementation aspects and evaluation of the performance of the solution through simulations and real-world experiments have been showcased. The findings demonstrate that the integration of PoET into IoV environments significantly enhances security without compromising efficiency, making it a promising solution for securing the next generation of connected and autonomous vehicles (CAVs).
