With the rapid development of quantum technologies and the growth of complex cyber threats, it is particularly important to create reliable data protection methods that can guarantee the unconditional security of transmitted information.Quantum cryptography works based on stuff like superposition (the ability of particles to be in several states at once), quantum entanglement (how they're connected from a distance), and the fact that it's impossible to exactly copy or change a quantum state.The application of these principles makes it possible to implement quantum key distribution, which ensures the detection of any interference in the communication channel and makes it impossible to intercept information unnoticed.The article analyzes the most well-known quantum cryptographic protocols, in particular BB84 and E91, their architecture, principles of operation, and features of implementation in military conditions.The composition of typical quantum protection systems is considered: light pulse sources, channels for transmitting quantum data, devices for receiving them, information processing modules, and conventional communication channels for control.The issues of compatibility of quantum solutions with the existing infrastructure of military telecommunications systems are considered, and the prospects for hybrid cryptographic models combining quantum and post-quantum approaches are analyzed.A comparative analysis of traditional and quantum cryptography is carried out according to criteria such as reliability, scalability, resistance to attacks, and development potential.The main advantages of using quantum cryptography in the defense sector are highlighted, in particular, ensuring a secure command communication channel, protecting navigation and telemetry systems, and the secure operation of distributed networks in combat conditions.Examples of international developments and research are considered, in particular, the DARPA Quantum Network, the Chinese Micius satellite, and EU projects within the Quantum Flagship initiative.These examples demonstrate the interest of leading countries in introducing quantum technologies into the field of national security.The potential of quantum cryptography as a means of updating and strengthening the cyber defense system in № 8(49) 2025 1018 the defense sector has been identified, taking into account both current challenges and future threats in the digital environment.
Quantum protocols for generating shared secret keys represent an effective method of ensuring secure information transmission using quantum communication channels. However, they are limited in scalability due to the physical constraints of quantum channels, which necessitates the use of classical communication channels for exchanging information between participants. This leads to the necessity of developing security threat models and network protection, especially in the case of hybrid networks, where quantum channels are used alongside classical ones. The peculiarity of constructing quantum key distribution protocols is associated with the costliness of implementation and implies the inevitable use of classical communication channels for key distribution. This paper addresses the task of ensuring the security of communication between subscribers not directly connected by quantum channels, through intermediary nodes, and analyzes threats from internal and external adversaries. Special attention is paid to situations where both types of adversaries have information about the processes and protocols in the network. The paper examines widely used key distribution protocols employed in practice. It describes the main security requirements applied to key distribution protocols, and presents the results of an analysis of the compliance of the discussed protocols with these requirements
The exponential growth of global telecommunication networks has heightened the need for robust security frameworks to protect data transmission against evolving cyber threats.Traditional encryption techniques, such as RSA and AES, while effective, are increasingly vulnerable to advances in computational power and the impending threat posed by quantum computing.Quantum cryptography, specifically Quantum Key Distribution (QKD), presents a revolutionary approach to securing telecommunication systems by leveraging the fundamental principles of quantum mechanics.Unlike classical encryption methods, QKD guarantees data security through the use of quantum states that are inherently resistant to interception and eavesdropping due to the no-cloning theorem and Heisenberg's uncertainty principle.From a broader perspective, this paper explores the integration of quantum cryptographic protocols into existing telecommunication infrastructures, emphasizing their potential to safeguard data transmission in fiber-optic and satellite communication networks.It examines the architecture and operational mechanisms of QKD systems, detailing protocols such as BB84 and E91, and evaluates their effectiveness in countering both classical and quantum-enabled cyber-attacks.Additionally, the study delves into the challenges of large-scale deployment, including key distribution range limitations, hardware requirements, and the need for quantum repeaters to support long-distance secure communication.Narrowing the focus, case studies on the implementation of quantum cryptography in 5G networks and global telecommunication hubs are analysed, highlighting their role in enhancing network resilience and ensuring end-to-end encryption.The paper concludes with strategic recommendations for policy development, international standardization, and future research directions to facilitate the widespread adoption of quantum cryptography in the telecommunications sector.
The analysis of the foundations of modern cryptographic systems is carried out. Problems of classical cryptography arising in the development of quantum computers are considered.

The analysis of stands for simulation of quantum key distribution available on the market is carried out. The rationale for the need to develop a training system has been made. The authors have developed a system for modeling and demonstrating quantum cryptographic protocols BB84, B92 and BB84 (4 + 2), intended for a detailed study of the principles of quantum cryptographic protocols in dynamics. The system provides the process of work both in text and graphic form. The developed system fully meets the needs of teaching students modern quantum information security technologies.
The main purpose of quantum key distribution protocols is to provide a practical and secure transmission of the single-use key used in encryption at the sender and receiver side. In the classical method, both parties cannot be sure that the key has not been taken over by an attacker. Since the quantum key exchange method basically relies on quantum physics, it provides higher security than conventional key distribution methods. In this study, the first and most used BB84 protocol, which is one of the quantum key distribution (QKD) protocols, and the distribution of the key between the receiver and the sender in the simulation environment and the attempt of the attacker to achieve the key was performed in the simulation environment. The results obtained in the last section are analyzed and suggestions are made for future studies.
