Abstract

The applied and theoretical aspects of quantum-cryptographic technologies are considered. The inter­related elements that make up the concept and content determined by the application of quantum cryptog­raphy are analyzed. The systematic analysis of quantum algorithms, quantum cryptography and quantum hashing are presented. The development of specialized quantum computers, focused on solving crypto­graphic problems is justified. The forecast of development of the field of quantum communication is done. The immediate prospects for the development of means of quantum cryptographic key distribution, quantum communication channels, channels of communication based on quantum teleportation, quantum networks of high-precision synchronization for secure management systems are highlighted. The independent signifi­cance of quantum random number generation is noted.

QUANTUM CRYPTOGRAPHY AS A NEW APPROACH TO PROTECTING CRITICAL DATA IN MILITARY TECHNOLOGIES

Oleksandr Gromovskyi

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.

State-of-the-art analysis of quantum cryptography: applications and future prospects

Swastik Kumar Sahu, Kaushik Mazumdar

Quantum computing provides a revolution in computational competences, leveraging the principles of quantum mechanics to process data in fundamentally novel ways. This paper explores the profound implications of quantum computing on cryptography, focusing on the vulnerabilities it introduces to classical encryption methods such as RSA and ECC, and the emergence of quantum-resistant algorithms. We review the core principles of quantum mechanics, including superposition and entanglement, which underpin quantum computing and cryptography. Additionally, we examine quantum encryption algorithms, particularly Quantum Key Distribution (QKD) protocols and post-quantum cryptographic methods, highlighting their potential to secure communications in the quantum era. This analysis emphasizes the urgent need for developing robust quantum-resistant cryptographic solutions to safeguard sensitive information against the imminent threats posed by advancing quantum technologies.

Quantum Cryptography: Advancements and Applications in Securing Networking Systems

Mohan Garg, Kambam Vedantan, I. Rexiline Sheeba +3 more

Quantum cryptography is an advanced technology that applies the principles of quantum mechanics to provide secure communication networks. Quantum crypto differs from other forms of cryptographic security that rely on mathematical theory because this allows quantum mechanics, the uncertainty principle and entanglement to enhance secure communication. Quantum cryptography has made significant progress recently and can effectively be used for networking system protection. Such advancement is the quantum key distribution protocol, where two parties generate the secret key to secure communication completely unshakable by any third party. One more advancement is the use of quantum teleportation, which allows transferring information between distant quantum systems without physically moving there. These developments have provided abundant opportunities for applications of quantum cryptography to secure networking systems. It helps maintain the secure transmission of sensitive information online or protects financial transactions and government and military communications. Quantum cryptography can also be used for secure authentication and access control, useful in cross-industry applications. Quantum cryptography is the best technology for implementing secure networking systems; thanks to its crypt-like harmony, it can be integrated into the most insecure networks with very rare error rates.
