Potential adversary and maliciously-behaved vehicles may cause traffic chaos or even lead to traffic accidents (particularly on traffic congestion crossroads). To address this issue, a novel security scheme is proposed for facilitating an efficient vehicular communication by employing a quantum secret sharing method. In the proposed scheme, the traffic control information is broadcasted regularly and shared among vehicles to reduce traffic congestion, and thus avoiding traffic accidents. Finally, we also demonstrate the superiority performance of our proposed scheme through theoretical and numerical simulation analysis.

In foggy highways, the secure vehicular communication system can be very important in preventing traffic chaos, congestion, and accident; however, potential attackers may hack this system that can create many problems in controlling or managing the traffic. In this paper, we propose a quantum cryptographic protocol for secure vehicular communication for foggy highways, which is unconditionally secure against outside and participant attacks. The outside attacks include intercept, intercept-resend, entangle-measure, man-in-the-middle, collective, Trojan horse, and coherent attacks; whereas, the participant attacks include the collusion, forgery, and collision attacks. In this protocol, the traffic control system broadcasts the information regularly so that the vehicles can take appropriate action and avoid traffic chaos, congestion, and accidents. This protocol can be used on busy and foggy highways such as the interstate-75 highway in the United States, M4 motorway in England, Tohoku Expressway in Japan, and Yamuna Expressway in India to prevent vehicle collisions. Quantum cryptographic protocol for secure vehicular communication is important because they provide a highly secure method of communication that is immune to eavesdropping and interception. The motivation for developing the quantum cryptographic protocol for secure vehicular communication comes from the growing need for secure communication in the digital age.
A secure vehicular communication system is crucial for preventing vehicle collisions on foggy highways; however, unconditionally powerful attackers can be the reason for vehicle chaos and accidents. Quantum cryptographic protocols offer a solution by leveraging the principles of quantum mechanics to provide inherently secure vehicular communication. The existing protocols cannot prevent quantum computer attacks. These protocols also require more computation costs. In this paper, we proposed a quantum protocol for vehicular communication based on Nash equilibrium, which can prevent quantum computer attacks. We use the Nash equilibrium to resist the collusion attack. In this protocol, we considered quantum attacks and computation costs as the performance parameters. The computation cost of this protocol isO(1)as the TCS only needs to perform a one-time computation for sharing the secret signal. In our protocol, the share of secret signals is regularly transmitted to the vehicles, and vehicles jointly compute the secret signals to avoid vehicle chaos and accidents. The proposed protocol can be deployed on foggy highways to avoid vehicle chaos and accidents.
Abstract In this study, a quantum secret sharing protocol based on mutually unbiased bases and its characteristics is proposed, and the implementation of the protocol is described in detail in the vehicular network environment. The protocol uses road condition information as the secret signal, which is distributed by the Traffic Control System. Vehicles participating in secret recovery can obtain road condition information, allowing them to plan their routes in advance and effectively avoid more severe traffic issues. The protocol employs two unitary matrices to encrypt data in a mutually unbiased basis and publishes the hash value of the data, ensuring unconditional security against both internal and external threats. The key rate serves as a critical parameter for proving the security of our protocol. A comprehensive analysis of the key rate's performance is conducted in relation to detection efficiency, depolarization probability, and transmission distance. Additionally, this study provides a security analysis supported by mathematical proofs. Compared to similar protocols, this protocol offers higher efficiency and requires shorter computation time, thereby enabling more efficient transmission of traffic signals and reducing traffic congestion and other related issues.
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.
Vehicular ad hoc networks (VANETs) connect numerous vehicles, allowing efficient vehicle-to-vehicle communication through a dedicated network. The dynamic connectivity of VANETs facilitates spontaneous communication among diverse vehicles, enabling real-time exchange of crucial information like traffic conditions, road hazards, and other pertinent data. This collaborative network enhances road safety and traffic efficiency by enabling vehicles to share information and adapt to changing conditions in their proximity, ultimately improving the overall transportation system. This paper proposes an authentication protocol designed to be unconditionally secure against quantum attacks. The research delves into integrating quantum authentication with blockchain technology to establish a secure framework for VANETs. We introduce a quantum blockchain framework focused on bolstering the security of VANETs. The paper provides a thorough analysis of the potential of quantum blockchain in addressing common security threats in VANETs, including data tampering, eavesdropping, and unauthorized access.
Quantum secret sharing is a fundamental technique in quantum cryptography. However, in practical quantum networks, it still faces several bottlenecks, such as high quantum communication cost and low transmission efficiency. To reduce the communication cost, ramp quantum secret sharing schemes have been proposed in existing studies. Nevertheless, intermediate sets in such schemes may leak partial information about the secret. To address this problem, this paper presents a method for detecting intermediate sets. Based on this method, we further propose a communication-efficient perfect quantum secret sharing scheme with eavesdropping detection capability.We analyze the communication cost under different numbers of participating parties and determine the range of participants that minimizes the reconstruction communication cost. The results verify the communication efficiency and security of the proposed scheme.
