Quantum resistant blockchain and deep learning revolutionize secure communications for autonomous vehicles

The blistering appearance of autonomous vehicle networks (AVNs) represents extreme cybersecurity dangers, particularly with the forthcoming danger of quantum computing, which is capable of overcoming traditional defenses on the basis of cryptography. This paper offers a new architecture that integrates quantum-resistant blockchain technology and deep learning to offer excellent cybersecurity in intelligent transportation systems (ITS). Three contributions are proposed: (1) a postquantum safe communication scheme, which will secure vehicle-to-anything (V2X) communications; (2) a decentralized blockchain-based data-sharing system, which will be utilized to ensure the integrity, privacy, and integrity of vehicular data; and (3) the application of a deep learning model as an anomaly detector and real-time threat mitigation to vehicle-to-anything (V2X) communications. The experimental tests demonstrate that the deep learning architectures for detecting cyber threats are 95.2% accurate, 94.1% precise, and 93.5% recall, with blockchain data integrity of 99.9% throughput of 150 transactions per second and a block validation time of 1.5 s. In context, the framework will help improve ITSs by offering safer roads, efficient communication infrastructure, and efficient data exchange, which will establish the road to successful and safe application of autonomous transportation systems in the real world.
