Internet of Vehicles (IoV) is a hot research issue at home and abroad. However, with the development of intelligent, sharing and network connection of IoV technology, the security protection of IoV communication has become a focus. Traditional encryption technology relies on encryption systems, whose security relies on the difficulty of solving mathematical problems and cannot resist quantum computing attacks. The security of classical encryption-based data transmission has been challenged. Therefore, it is imperative to realize secure transmission in IoV based on quantum technologies such as quantum teleportation. In this paper, based on the secure transmission of shared secret states, the author has designed a model for the secure transmission of data among multiple vehicles, which does not require trusted client nodes and thus improves the performance against node attacks. Further, considering the communication distance in practical situations, the quantum repeater is introduced to construct a quantum state transmission model based on the quantum repeater in IoV to realize secure communication among multiple vehicles. Compared with traditional data transmission, the quantum state transmission data is more secure and unbreakable, which provides a new idea for constructing secure communication in IoV.

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.
With the rapid development of information science, the privacy protection of medical data has been paid close attention. Given that traditional encryption technology has some technical loopholes in the intractability of large prime number factorization and information transmission security, the security of medical data transmission based on classical encryption is challenged. Thanks to the uncertainty principle and quantum non-cloning theorem, quantum communication technology is relatively secure. The secure quantum state transfer protocol is also a popular topic in information transmission now. Thus, based on quantum technologies such as quantum teleportation, it is imperative to realize safe transmission in smart medical care. Based on the secure transmission of shared secret states, this paper designs a secure transmission model of medical data between multiple clients and servers, which does not need a trusted client node, thus improving the performance of resisting node attacks. In addition, by using qiskit, the protocol simulation is conducted. Compared with traditional medical data transmission, quantum state data transmission is more secure and undecipherable, achieving the secret transmission of medical data.
With the continuous progress of technologies such as lasers, electronics, and computers, their practical applications have also made great progress. Quantum Key Distribution (QKD) is currently one of the most promising quantum teleportation technologies and a hot topic in the field of secure communication. The purpose of this article was to study the application of quantum teleportation technology in the Internet of Vehicles (IoV). This article fully explained the concept, principles, and methods of quantum teleportation technology, deeply understood the absolute security attributes of quantum teleportation technology, and then pointed out its practical operability in the field of information security by introducing its development status and application prospects. Based on the security needs of the IoV and considering the shortcomings of existing security protection technologies, the risks of the IoV and the urgent need for high security of information technology were highlighted. A persistent and secure bidirectional authenticated QKD protocol was proposed, and simulation experiments were conducted on the NS-2.45 network simulation platform. The experimental results showed that the average time cost of this scheme was only 0.11 seconds when the number of vehicles was 10. Compared with other similar schemes, this scheme had lower overhead.
The Internet of Vehicles (IoVs) is one of the most popular techniques among the applications of Internet of Things. The existing IoVs are mainly protected by public key cryptographic systems, which provide identity authentication and information security. Nevertheless, using the proposed Shor's algorithm, the security of all classical cryptographic schemes will be exposed to future quantum computer technologies. Fortunately, based on the unconditional security property of quantum mechanics, direct communication protocols can resist quantum computer attacks and deliver secret messages directly without the requirement of pre-shared keys. For IoV networks, we present a continuous-variable quantum secure direct communication (CV-QSDC) protocol in which the orbital angular momentum (OAM) is used as the information carrier. For one thing, the field of continuous-variable quantum communication system is compatible with the standard telecommunication technology; for another, orbital angular momentum eigenstates for coding possess higher information capacity.
The Internet of Vehicles (IoV) has the potential to improve the efficacy and safety of transportation, but it is also vulnerable to a variety of security threats. Traditional cryptographic methods are susceptible to vulnerabilities amid the imminent threat of quantum computation. In order to establish secure communication channels, this chapter investigates the integration of Quantum Key Distribution (QKD) into IoV. It explores the principles of QKD, its advantages over classical cryptography, and the obstacles associated with its implementation in vehicular networks. Key management strategies are examined in the chapter, which also provides a thorough examination of QKD protocols that are appropriate for IoV. Additionally, it examines practical aspects, including resource optimization, error correction, and the establishment of quantum channels. This research safeguards critical vehicle-to-vehicle and vehicle-to-infrastructure communications by addressing these challenges, thereby contributing to the development of robust and secure IoV systems.
ABSTRACT With the rapid advancement of Internet of Vehicles technology (IoV), secure vehicle communication has become a core requirement for intelligent transportation systems. However, traditional cryptographic protocols face limitations in security, particularly against potential quantum computing attacks. This paper proposes an authenticable threshold quantum secret sharing protocol for secure vehicle communication. In this scheme, a traffic control system acts as the dealer, encoding traffic status or control commands into single‐photon states and distributing them to uniquely identified vehicles. Any vehicles within the vehicle cluster can collaboratively reconstruct the secret. Analysis shows that the protocol satisfies correctness and is resistant to common attacks, including intercept‐resend, entangle‐measure, man‐in‐the‐middle and Trojan horse attacks. Performance analysis quantifies the effect of noise on the transmission of quantum states and provides guidance for the choice of quantum states. Compared with existing vehicle security protocols, the proposed scheme demonstrates advantages in security and efficiency, making it suitable for high‐security IoV scenarios such as foggy highways and cooperative driving.
