Enhancing Security in Intelligent Transport Systems: A Blockchain-Based Approach for IoT Data Management

In intelligent transport systems (ITS), an interconnected Internet of things (IoT) device operates autonomously, collecting and exchanging data without human intervention. While the ITS offers numerous benefits, it also introduces various cybersecurity risks. These risks include the potential for undetected malicious IoT sensors, vulnerabilities in authorization and authentication protocols, and insecure data management practices. Therefore, it is crucial to develop new solutions that enhance the security of IoT sensors to address these challenges effectively. One specific challenge is securely managing and storing IoT data in intelligent transport systems. Current centralized systems are susceptible to tampering, necessitating more reliable data traceability records. This chapter proposes a blockchain-based architecture for securing and managing IoT data in ITS, offering advantages like immutability, decentralization, and enhanced security. Our results show that the proposed architecture performs well and can efficiently store vast amounts of IoT data. Additionally, it allows seamless addition and removal of new IoT sensors without retrofitting. Moreover, it is versatile and applicable to any intelligent transport system application. In conclusion, this architecture provides a robust and secure solution, significantly enhancing the overall security of IoT devices in this domain.
