    SSL/TLS protocol on post-quantum algorithms
    (Національний авіаційний університет, 2024) Milevskyi, Stanislav; Voropay, Natalya; Korol, Olha; Yevseiev, Serhii; Aksonova, Iryna
    The development of mobile technologies and their integration with Internet of Things and smart technologies form both cyber-physical and socio-cyber-physical systems. In such systems, as a rule, wireless communication channels are used, in which SSL/TLS protocols are used to provide security services (confidentiality, integrity and authenticity). However, this protocol is not only vulnerable to "Meeting in the Middle", POODLE, BEAST, CRIME, BREACH attacks, but with the advent of a full-scale quantum computer, it can be broken. The article proposes a protocol based on quantum algorithms – crypto-code constructions, which will ensure not only resistance to current attacks, but also stability in the post-quantum period. To ensure the "hybridity" of services, it is proposed to use McEliece and Niederreiter crypto-code constructions and the improved UMAC algorithm based on McEliece crypto-code design. The use of crypto-code constructions provides not only resistance to attacks, but also simplifies the formation of a connection – the parameters of elliptic curves are used for the transmission of the common key. This approach significantly reduces the time of connecting mobile gadgets and simplifies the procedure of agreement before data transfer.

    Development of the double-contour protection concept in socio-cyberphysical systems
    (Національний технічний університет "Харківський політехнічний інститут", 2022) Pohasii, Serhii; Milevskyi, Stanislav; Tomashevsky, Bohdan; Voropay, Natalya
    The rapid development of mobile Internet technologies LTE (Long-Term Evolution) not only predetermined the further development of cyber-physical systems, which are based on the synthesis of technologies of classical computer systems and LTE technologies, as well as integration with Internet-of-Things technologies. As a result, the emergence of sociocyberphysical systems predetermines further development based on this integration. The creation of mesh- and sensor networks also allows the development of smart technologies and systems based on their conglomeration. The development and creation of a quantum computer, on the one hand, will make it possible to make a technical breakthrough in computing resources, use artificial intelligence, and on the other hand, it can lead to "chaos" in ensuring the security of modern technologies and systems. So, based on the algorithms of Shor and Grover quantum cryptography, symmetric cryptosystems based on traditional cryptography algorithms, as well as asymmetric cryptosystems, including systems based on elliptic curve cryptography, can be broken. The paper proposes to use a new approach to building security systems based on the concept of internal and external security contours. At the same time, security contours of continuous business processes are considered. This approach provides an objective assessment of the current state of security of the socio-cyber system as a whole.
