This paper aims to take a new look at a novel security solution for 5G-based Internet of things (IoT) networks using quantum key distribution (QKD). Quantum keys are created and sent from a key distribution server to IoT gateways thanks to radio-over-fiber (RoF) systems. More specifically, the raw key is encoded into the intensity of radio-frequency subcarrier before being sent to the gNB by optical fiber. It is then wirelessly forwarded to IoT gateways through radio frequency links. The major findings of the study reveal that the proposed system is an effective approach in order to distribute the quantum key with low quantum bit error rate and high secret key rate for 5G-based IoT networks.

The rapid proliferation of Internet of Things devices (IoT) across healthcare, smart homes, transportation, and industrial automation has led to an unprecedented exchange of sensitive data over wireless channels, exposing these networks to cyberattacks, eavesdropping, and unauthorized access.Conventional cryptographic techniques, which rely on computational hardness assumptions, are increasingly vulnerable to the emerging capabilities of quantum computing.This paper explores the application of Quantum Key Distribution (QKD) as a means of enabling secure and dependable data communication for IoT devices.By exploiting the fundamental principles of quantum mechanics, QKD allows two communicating parties to generate a shared secret key while inherently detecting any attempt at interception.The proposed approach aims to enhance data privacy, ensure secure authentication, preserve confidentiality, and safeguard IoT systems against present and future quantum enabled threats.The integration of quantum based security techniques into existing IoT infrastructure is examined, along with its implications for improving the reliability and trustworthiness of wireless IoT communication systems.This work positions Quantum Enhanced Secure Data Communication as a forward looking security solution for next generation IoT networks.
Current cryptographic techniques broadly specified as conventional cryptography is solely based on the solidity of the mathematical concepts. The advancements in quantum computing can use reversible logic to compute the keys and easily break the existing security in conventional computers. From the analysis of the network structure of Internet of Things (IOT) it is very clear that the entire backbone of the system would collapse if it is attacked or hacked. IOT is a wireless technology that connects “ANYTHING” around to the Internet. IOT is a revolution which should be protected from the attackers as it would lead to several losses which could even be fatal. Hence a strong provision for securing users data in IOT is a real challenge. This paper is attempted to review the fundamentals of Quantum Key Distribution, security aspects for IOT and to address how QKD can be used to secure a IOT system. The challenge encountered is to increase the range and increase the transmission rate of data in QKD systems and to check for a possible solution to adhere these systems with existing information security solutions
The fast development of Internet of Things (IoT) devices has introduced unknown security issues in the networked systems. Classical cryptography methods are restricted to sophisticated attacks and the emerging threat of quantum computing. This survey paper presents the overview of quantum key distribution (QKD) use in IoT settings, systematic review of the research trend, technological solutions, challenges, and future developments. We examine more than 150 published in-between 2018-2025 research papers, categorize the current QKD-IoT solutions, and uncover gaps in the research. We find that hybrid QKD-classical cryptography designs provide promise of realistic IoT implementation and edge-based quantum gateways emerge as an architecture of scalable implementation.
The Internet of Things (IoT) connects billions of machines that can interact with each other. IoT is one of the fastest-growing areas in the history of computing, and will continue in this direction in the 6G era. New security problems have been raised, however, since implementing protection mechanisms for IoT devices, such as encryption, authentication, and so on, is inefficient, due to their inherent flaws. Therefore, a new method of protecting IoT devices needs to be sought. Quantum security depends on the natural physical phenomenon (quantum mechanics) and offers an appropriate and powerful security technique. This paper suggests a new approach for simulating the quantum key distribution between IoT devices and a server to encrypt the data sent to the server. It also demonstrates the simplicity of this new method, and its efficiency in producing a quantum key distribution (QKD) simulation. In addition, it describes the use of the final length key for symmetrical security for IoT devices. Moreover, the simulation of the attacker between the server and IoT devices is performed.
Conventional cryptography relies only on the robustness of mathematical principles. Advancements in quantum computing may use reversible logic to calculate keys and easily compromise the security of traditional computers. The examination of the Internet of Things (IoT) network topology reveals that the whole system's backbone would disintegrate if subjected to an assault or hacking attempt. The Internet of Things (IoT) is a wireless technology that links various objects to the Internet. The Internet of Things (IoT) represents a revolution that must be safeguarded from attackers, since breaches might result in significant, perhaps deadly losses. Consequently, ensuring robust protection of user data in IoT is a significant problem. This study aims to explore the principles of Quantum Key Distribution, examine security considerations for the Internet of Things, and discuss the use of QKD in securing IoT systems. The problem faced is to enhance the range and transmission rate of data in Quantum Key Distribution (QKD) systems, while also exploring potential methods to integrate these systems with current information security measures.
Internet of Things (IoT) deployments face significant security challenges due to the limited energy and computational power of IoT devices. These challenges are more serious in the quantum communications era, where certain attackers might have quantum computing capabilities, which renders IoT devices more vulnerable. This paper addresses the problem of IoT security by investigating quantum key distribution (QKD) in beyond 5G networks. An architecture for implementing QKD in beyond 5G IoT networks is proposed, offloading the heavy computational tasks to IoT controllers, while considering the use case of sensors deployed in railroad networks. Neural Network (NN) techniques are proposed in order to detect the presence of an attacker during QKD without the need to disrupt the key distribution process. The results show that the proposed techniques can reach 99% accuracy.
