The article provides an overview of the digital technology quantum communication and its place among end-to-end digital technologies. Also the problem of quantum threat to the information security of the Russian Federation is considered. The cryptography used today is based on discrete logarithms or factorization, which will lose their cryptographic strength after the implementation of a quantum computer. All countries have started to analyze and develop new information security technologies which are capable to ensure its confidentiality in the quantum era.The article analyzes the experience of building a new information security system in several countries (Great Britain, the European Union, the USA, China). The analysis made it possible to evaluate Russian actions in this area, as well as to identify shortcomings in the regulatory framework governing quantum cryptography, which include quantum key distribution, quantum random number generator, post-quantum cryptography.The author substantiates the need for the introduction of an experimental legal regime and the creation of the «cryptographic agility». The implementation of these proposals will help to prepare a regulatory framework for data migration to an environment protected by cryptographic ciphers resistant to quantum computing. The quantum communication is a new way to protect information in a digital state, where data plays a key role, and their confidentiality and integrity become the key to national security.

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.
The advent of quantum computing presents unprecedented challenges to traditional cybersecurity measures, particularly in the realm of encryption.This paper explores the emerging field of quantum cryptography, which leverages the principles of quantum mechanics to develop advanced encryption methods that are inherently secure against the threats posed by quantum computing.By utilizing phenomena such as superposition and entanglement, quantum cryptography enables the creation of cryptographic keys that are provably secure, as any attempt to intercept or measure the quantum state of the key will result in detectable anomalies.The study examines various quantum cryptographic protocols, including Quantum Key Distribution (QKD) and post-quantum cryptography, highlighting their potential to safeguard sensitive data in various applications, from financial transactions to secure communications.Additionally, the paper discusses the implications of quantum cryptography for existing cybersecurity strategies, emphasizing the need for organizations to adapt to this rapidly evolving landscape.By addressing the challenges and opportunities presented by quantum technologies, this research aims to provide insights into the future of cybersecurity and the critical role quantum cryptography will play in protecting data integrity and privacy in an increasingly digital world.
The uses of computer communications networks technologies have increased the incidents of computer abuse. Because of these incidents, most organizations facing pressure to protect their assets. Most digital networks generally rely on modern cryptosystems to secure the confidentiality and integrity of traffic carried across the network. The current modern cryptosystems based on mathematical model introduce potential security holes related to technological progress of computing power, the key refresh rate and key expansion ratio, the most crucial parameters in the security of any cryptographic techniques. For that reason efforts have been made to establish new foundation for cryptography science in the computer communications networks. One of these efforts has led to the development of quantum cryptography technology, whose security relies on the laws of quantum mechanics [1,2,3,20, 24]. This research paper concentrates on quantum cryptography, and how this technology contributes to the network security. The scope of this research paper is to cover the weaknesses, and the security pitfalls in modern cryptography, fundamental concepts of quantum cryptography, the real - world application implementation of this technology, finally the future direction in which the quantum cryptography is headed forwards.
The article examines the significant transformation of the concept of information and its impact on modern security technologies. Until the middle of the 20th century, the concept of information was considered as a philosophical category related to the transfer of knowledge and meaning. With the advent of Claude Shannon's communication theory, information was reinterpreted as a measurable and transferable quantity, which opened up new horizons for the development of fields such as coding theory and cybernetics. The introduction of the bit as a unit of information measurement allowed for a more accurate analysis of data transmission processes. Landauer and Bennett's research has shown that information has a physical nature, closely related to energy and entropy. In recent decades, the concept of information has begun to play an important role in quantum theory, which has given rise to such areas as quantum information and quantum cryptography. In the face of increasing cybersecurity threats, quantum cryptography can become a reliable basis for protecting critical information systems. Existing post-quantum algorithms, although they have larger keys, can serve as a substitute for traditional security systems. The development of new standards and the transition to post-quantum security methods are becoming important steps to ensure data security in the near future. Quantum cryptography offers not only adaptation to new challenges, but also a fundamentally new level of security previously inaccessible to classical cryptographic systems, which makes it a key element for data protection in the future. Conclusion. The presented work demonstrates the evolution of the concept of information from a philosophical abstraction to a practical and measurable entity in the field of computer science, physics and cryptography. The article highlights the importance of quantum cryptography as a means of protection against future threats in the field of cybersecurity, offering both a theoretical and practical basis for protecting critical information. Taking into account the further development of quantum information science, its impact on data security and protection will have a significant impact on the formation of future cybersecurity strategies in various industries.
