Enhancing Intelligent Transport Systems through Quantum and blockchain security in vehicular networks

Intelligent transportation systems (ITSs) rely heavily on vehicular networks, which bridge the gap between vehicles and facilities via strong decentralized communication, enhancing traffic management and road safety. Still, the trustworthiness and protection of vehicle interactions are at risk due to decentralization's introduction of security flaws such as spoofing, manipulation, and denial-of-service attacks. Such decentralized networks typically need scalability and real-time reaction, neither provided by traditional centralized security procedures. According to this study, distributed and real-time technologies like blockchain and secure multi-party computing make communications safer and more private. Eliminating a single point of failure improves system resilience. Quantum computing has made traditional encryption more vulnerable to attacks, requiring more complex security techniques. An innovative Quantum Blockchain-based Secured Vehicular Network (QBS-VN) system was suggested in the study. This system would leverage blockchain technology for worldwide authentication and data integrity, as well as Quantum Key Distribution (QKD) for unbreakable encryption. Safeguarding vehicle network communications from eavesdropping, unauthorized access, and data manipulation is the proposed QBS-VN architecture. To guard against growing electronic threats, employ Post-Quantum Cryptography (PQC). Traditional systems have latency issues, but our all-encompassing technology greatly improves danger detection. With few false positives, it detects abnormalities with 95% accuracy. In conclusion, vehicle network protection has improved.
