The emergence of quantum computing poses significant risks to conventional network security, prompting researchers to focus on developments in quantum cryptography, particularly Quantum Key Distribution (QKD).According to research, it has been found that traditional security methods, like RSA encryption, could potentially be at risk from quantum algorithms.On the other hand, quantum cryptography is a field of study that leverages the principles of quantum mechanics to improve the security of communication.One of the techniques used in quantum cryptography is Quantum Key Distribution (QKD), which makes use of the unique properties of quantum particles such as photons to securely distribute encryption keys and detect any potential eavesdropping attempts, thanks to the uncertainty principle.Nevertheless, the integration of QKD into current network infrastructures poses significant challenges due to the required technological advancements.This study offers a comprehensive analysis of the fundamental principles underlying quantum cryptography, the obstacles that arise during its implementation, and its potential prospects for protecting against the risks posed by advancements in quantum computing.Furthermore, this study delves into the potential consequences of these technological advancements across different industries and emphasizes the need to create algorithms that can withstand quantum attacks to guarantee strong data security in the age of digitalization.
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.

Modern powerful computing technology development threatens the confidentiality of information that usually provided by traditional cryptographic means and forces researchers to look for alternative security methods. Given the current trends, these alternatives may be quantum cryptography and communication methods. These methods unlike traditional (classical) analogues use specific unique properties of quantum particles and are based on the inviolability of the quantum physics laws. Existing classifications in quantum cryptography and communications do not include the large number of modern methods. It complicates its study and use in the quantum information security systems development. In the paper modern methods of quantum cryptography and communication were analyzed, their advantages and disadvantages, security assessment to various kinds of cyberattacks were defined, and also the existing classifications of these methods were studied. On the basis of partial generalizations of theoretical positions and practical advances in quantum cryptography, the generalized classification of quantum cryptography and communication methods was constructed. This classification reveals a problem in this area and can extend the possibilities for choosing the appropriate methods for modern quantum information security systems development.
