Blockchain Security for IoT Devices in Autonomous Vehicle Networks

Abstract

The integration of Internet of Things (IoT) devices in autonomous vehicle networks (AVNs) has revolutionized transportation by enhancing communication and real-time decision-making. However, this increased connectivity also raises significant security concerns, as IoT devices are vulnerable to data breaches, tampering, and unauthorized access. Blockchain technology, with its decentralized and immutable structure, offers a promising solution for enhancing security in these networks. This paper explores the application of blockchain in securing IoT devices within AVNs, focusing on its ability to ensure data integrity, protect privacy, and provide decentralized security mechanisms. A detailed analysis of blockchain’s architecture, including its consensus mechanisms and smart contracts, is presented. The paper also highlights the challenges, such as scalability and resource constraints, associated with blockchain implementation in IoT environments. Additionally, potential solutions, including lightweight blockchain protocols and integration with edge computing, are discussed. By addressing these challenges, blockchain technology can significantly improve the security and resilience of IoT devices in AVNs, ensuring safer and more reliable autonomous transportation systems.
