DS21 - Sergiy Gnatyuk - QKD-based Security for 5G and Next Generation Networks

The implementation of modern information and communication technologies (ICT) in all spheres of human activity, as well as the increasing number and power of cyber-attacks on them makes the cyber security of the developed digital state vulnerable and weak. Cyber-attacks become targeted (so-called APT-attacks) and attackers carefully prepare them, analyzing the identified vulnerabilities and all possible ways of attack. The security and defense capabilities of the state are considered in an additional fifth domain titled cyberspace (after land, air, water and space), world`s leading states develop strategies to protect cyberspace, create cyber troops, develop and test cyber weapons. A significant number of cyber-attacks today are aimed at critical infrastructures and government organizations. Traditional security methods (in particular, cryptographic algorithms) do not fully protect against all currently known attacks. They are potentially vulnerable to attacks based on quantum algorithms (Shore's, Grover's, Deutsch-Jozsa etc). These methods are based on the fundamental impossibility of an attacker to solve some complex mathematical problem (unordered database search, factorization, logarithm in large discrete fields etc.) in polynomial time. But the increase in computational power of advanced ICT as well as potential "quantum computer in the hands of an attacker" is a security and privacy threat and it encourages the search for alternative security methods. Such alternative approaches can be methods of quantum and post-quantum cryptography. Quantum Cryptography (Quantum Key Distribution, QKD) does not depend on the computational power of an attacker, uses the specific unique properties of quantum particles and is based on the inviolability of the laws of quantum physics. The main advantages of QKD are the ability to define an attacker and ensure information and theoretical security. QKD includes the following protocols: protocols using single (non-entangled) qubits and qudits (d-level quantum systems); protocols using phase coding; protocols using entangled states; decoy states protocols and others. World`s leading QKD company ID Quantique has developed many QKD systems, QRNGs, Quantum-Safe security devices as well as implemented these systems in 5G deployment projects with SK Telekom, British Telecom, Deutsche Telecom and other cellular operators. Today QKD is an important part of 5G and next generation networks. At DeepSec, a QKD-based security system will be presented and analyzed. Impact of Quantum computing on cryptography (secret key cryptography, public key cryptography, hash functions) will be assessed and analyzed. Author`s QKD / QSDC protocols and additional security procedures will be presented. The methods of QKD integration into different 5G network slices will be shown and explained. Sergiy Gnatyuk holds a PhD and DSc (second academic research degree in Ukraine) in cybersecurity, he is a professor of Computer Science. Sergiy is Professor and Vice-Dean of the Faculty of Cybersecurity, Computer and Software Engineering at National Aviation University as well as Scientific Advisor of the NAU Cybersecurity R&D Lab cyberlab.fccpi.nau.edu.ua. Also, Sergiy is a cybersecurity expert and consultant for state and private Ukrainian and international organizations. He is a speaker and organizer of many international cybersecurity events as well as the author of many books, patents and papers. The topics of the papers and books are cybersecurity, QKD, 5G and NGN security, incidents response, CIIP and others.
