Hybrids in automatic vehicles have brought in aspects of security in intra-sensor communications never seen before. Most of these threats cut across the lengths of conventional cryptographic modes against the advance of quantum computing. The research paper introduces “Q-SafeAV”, which forms an altogether new quantum secure intra-sensor communication structure able to withstand threats specifically from autonomous vehicle (AV) networks. The approach incorporates quantum key distribution (QKD) protocols and post-quantum cryptographic algorithms in the formation of quantum secured channel for communication with informational theoretical security properties between vehicle sensors for ensuring information integrity and authenticity in real-time operational environments. The framework identifies important weaknesses today that exist in current automotive communication protocols while being able to meet stringent latency requirements that are extremely crucial for safety-critical applications. To test and validate the proposed methodology, extensive experimentation were conducted, and it was observed that “Q-SafeAV” shows processing latencies below 10 milliseconds provide it with enhanced security based on quantum mechanical principles, making it suitable for real-time applications in AVs. The experimental results provide quantum-safe protection against both current and future computational attacks. Overall, the research addresses a crucial portion of growing demands for quantum-resilient security frameworks in next-generation autonomous transportation systems.
The rise of autonomous vehicles (AVs) has led to an increased reliance on vehicle-to-vehicle (V2V) communication networks to ensure real-time information sharing, situational awareness, and cooperative decision-making. However, the integration of quantum computing into cybersecurity threatens the cryptographic foundations upon which current V2V communication protocols rely. As quantum computers grow closer to practical implementation, traditional public-key encryption schemes—such as RSA and ECC—are rendered vulnerable to attacks from quantum algorithms like Shor’s and Grover’s. This review explores the necessity of adopting quantum-resistant cryptographic protocols to secure V2V communication frameworks. The study critically examines post-quantum cryptographic algorithms, including lattice-based, hash-based, code-based, multivariate polynomial, and isogeny-based schemes, with a focus on their applicability to latency-sensitive and resource-constrained vehicular environments. Furthermore, the paper evaluates the performance, scalability, and implementation challenges of integrating these cryptographic primitives into real-time autonomous systems. Case studies of pilot implementations and emerging research are reviewed to highlight the practicality of these protocols in vehicular edge computing and 5G-enabled automotive networks. The paper concludes by proposing a forward-looking roadmap for standardization and integration of quantum-resilient cryptography in intelligent transportation systems (ITS), ensuring long-term data integrity, authentication, and privacy across V2V infrastructures.

The rapid integration of Internet of Things (IoT) technologies in Autonomous Vehicles (AVs) has significantly expanded the attack surface of vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication systems.These networks exchange large volume of safety-critical data in realtime, which increases their exposure to attacks like message tampering, identity spoofing, and coordinated injection.Traditional cryptographic systems become more suspectable to emerging quantum computing threats, whereas the existing intrusion detection systems suffer from high latency, static encryption, and increased energy consumption due to frequent vehicular movement.These challenges restrict the ability of current systems to guarantee secure, real-time, energy-efficient, and sustainable communication for next-generation AVs.To address these challenges, this study introduced a novel Quantum-Enhanced Lightweight Protocol (QELP) that combines hybrid quantum-classical security mechanisms with adaptive encryption orchestration to improve security, real-time performance, and sustainable operation in IoT-enabled autonomous vehicle sensor networks.QELP combines BB84based Quantum Key Distribution (QKD) and lattice-based post-quantum cryptography (Kyber+) to establish quantum-resilient session keys.The context-aware encryption method dynamically adjusts the encryption intensity and key refresh rate based on residual energy, traffic density, anomaly score, and vehicular mobility to balance security strength and computational overhead.The model includes multi-layer error and attack detection techniques, including quantum-based intrusion alerts, digital signature validation, and behavioural deviation checks.The VeReMi and CARLA-NS3 datasets are employed for message-based V2X attack validation and to assess the networklevel behavior under real-time traffic scenarios.The performance is evaluated by simulations using Python (Qiskit) for quantum layers and NS3 for AV networks.The simulation results outperform with 98.76% attack detection rate, 0.015 false alarm rate, 13.7ms latency, 12.2% energy depletion score, 94.6% security risk score reduction towards a stronger quantumresilient defense and an encryption throughput improvement to 96.8%, handling encrypted data at high speed.The findings confirm that QELP provides a scalable, quantum-resilient, and energy-aware security architecture for next-generation autonomous vehicular communication systems.
Advanced connection and autonomous features are being made possible by the Internet of Vehicles (IoV), which is causing a revolution in transportation. Strong security measures are required, however, because the prevalence of connected devices also increases the likelihood of cyberattacks and data breaches. This study introduces a new method for protecting IoV networks, which combines Blockchain technology with Quantum Key Distribution (QKD), creating a security architecture with two layers. Internet of Vehicles (IoV) technologies enable autonomous driving and real-time data exchange by connecting vehicles to infrastructure and one another. These advancements make things safer and more efficient, but they also put sensitive information at risk of cyberattacks. Modern security measures are essential since traditional encryption methods are becoming more and more insecure. To provide encryption that is theoretically unbreakable, the suggested system uses QKD to create and distribute cryptographic keys based on principles of quantum mechanics. To improve trust and transparency, blockchain technology is used to record these keys and any subsequent transactions in an immutable, distributed ledger. A hybrid architecture, with QKD securing the key exchange and Blockchain ensuring the integrity and authenticity of the communication, is designed as part of the integration process. Improved security and speed have been shown in simulations and prototype implementations of the QKD-Blockchain architecture in IoV networks. By preventing eavesdropping and key interception, the QKD technique kept the communication channel secure. With an average delay of only about 2 milliseconds, QKD performed admirably and was well below the permitted range for real-time vehicular communications. On average, validation durations for transactions were 5 milliseconds, which was a little overhead due to blockchain integration. The system efficiently handled up to 10,000 transactions per second without affecting security or performance, proving that it can serve massive IoV networks, according to scalability testing. Under high-load scenarios, the framework maintained consistent performance and security, proving its robustness in stress tests. Together, QKD and Blockchain provide a scalable and trustworthy option for future vehicular communication networks, and these results show how feasible and robust it is to use them to protect IoV systems. An intriguing approach to the security issues plaguing IoV systems is the integration of QKD with Blockchain technology. An unparalleled level of protection against cyber threats is provided by the dual-layered system, which guarantees strong encryption and data integrity. This fresh method may lead to improved and more trustworthy IoV networks by establishing new benchmarks for secure vehicular communication. In order to optimize the implementation and tackle any new issues that may arise, more research and development should be conducted.
Secure communication is crucial for intelligent infrastructure networks, especially in the field of vehicle-to-everything (V2X) communication. Real-time information ex change between vehicles is the cornerstone of traffic safety and intelligent decision making. However, existing V2X communication systems primarily rely on classical cryptographic security mechanisms, while the rapid development of quantum com puting fundamentally threatens their security guarantees. Quantum key distribu tion (QKD), based on the no-cloning principle of quantum mechanics, is considered a promising technology against quantum attacks. However, most existing studies focus on theoretical security analysis or static fiber optic transmission scenarios, lacking systematic evaluation of the complete QKD protocol workflow in highly dynamic V2X environments. To fill research gaps, this thesis constructs a vehicle-to-vehicle quantum key distribution (V2V-QKD) framework based on the Veins simulation platform, integrated with OMNeT++ and SUMO. The framework implements qubit preparation and trans mission, measurement, quantum bit error rate (QBER) estimation, error correction, and privacy amplification, aiming to evaluate the feasibility and robustness of QKD in dynamic V2V communication scenarios. This thesis designs two sets of experiments. The first set of experiments evaluates parameter robustness by varying the number of qubits transmitted in a single session and analyzing its impact on quantum error rate (QBER), final key length, and key generation rate. Experimental results show that when 𝑁raw = 800, the system achieves a favorable balance between QBER estimation stability and key generation reliability. The second set of experiments compares the performance of BB84 and SARG04 under gradually increasing eavesdropping and attack intensity. Results show that under no eavesdropping conditions, BB84 can stably generate longer keys, but its performance degrades significantly under attacks; while SARG04 generates shorter keys under ideal conditions, but remains relatively stable under increased attack interference. Comprehensive results demonstrate that, under optimized configuration, QKD can provide stable and secure key generation for V2V communication. Furthermore, an adaptive protocol selection strategy enhances system-level security resilience. This thesis verifies the feasibility of QKD in vehicular network environments and provides an experimental foundation and design reference for secure vehicular communication systems capable of withstanding quantum-era threats.
