Документ Analysis of the current status of intelligent system "Internet of Things" and trends in the development(НТУ "ХПІ", 2017) Goriushkina, Alla; Korolev, RomanThe subject of study in the article is the processes of analysis and evaluation of attack intelligent systems "Internet of Things" (IoT). The goal is to reduce the potential attacks due to the risks of intellectual functioning of the IoT systems, through the timely adoption of security measures. Objectives: the classification of attacks on all levels of intelligent systems, IoT, highlighting the main factors and their causes; the following results are obtained. The analysis of the current state of intelligent systems, IoT, analyzed all levels of functioning, and classification of hackers on the factors of their occurrence. The negative consequences negatively affecting the basic characteristics of the functioning of the IoT systems. As a result, a block diagram of attacks at all levels of the IoT. Conclusions. The article analyzes the current state of intelligent systems "Internet of Things" (IoT). It is shown that a significant increase in computer network devices connected to the network creates new opportunities for the development of modern society in the field of science and technology. However, the significant development of "Internet of Things" is directly proportional to increases the possibility of attacks in computer networks. Therefore, the scientific direction improvement of existing or development of new algorithms, models, and their implementation to ensure major safety criteria for IoT are relevant.Документ Modeling of security systems for critical infrastructure facilities(PC Technology Center, 2022) Yevseiev, Serhii; Hryshchuk, Ruslan; Molodetska, Kateryna; Nazarkevych, Mariia; Hrytsyk, Volodymyr; Milov, Oleksandr; Korol, Olha; Milevskyi, Stanislav; Korolev, Roman; Pohasii, Serhii; Tkachov, Andrii; Melenti, Yevgen; Lavrut, Oleksandr; Havrylova, Alla; Herasуmov, Serhii; Holotaistrova, Halyna; Avramenko, Dmytro; Vozniak, Roman; Voitko, Oleksandr; Yerhidzei, Kseniia; Mykus, Serhii; Pribyliev, Yurii; Akhiiezer, Olena; Shyshkin, Mykhailo; Opirskyy, Ivan; Harasymchuk, Oleh; Mykhaylova, Olha; Nakonechnyy, Yuriy; Stakhiv, Marta; Tomashevsky, BogdanThe development of Industry 4.0 technologies is based on the rapid growth of the computing capabilities of mobile wireless technologies, which has made it possible to significantly expand the range of digital services and form a conglomeration of socio-cyber-physical systems and smart technologies. The First Section discusses the issues of building security systems based on the proposed Concept of multi-contour security systems, taking into account the hybridity and synergy of modern targeted cyber-attacks, their integration with social engineering methods. This approach not only increases the level of security, but also forms an objective approach to the use of post-quantum security mechanisms based on the proposed Lotka-Volterra models. The Second Section analyzes the features of the functioning of social Internet services and establishes their role in ensuring the information security of the state. An approach is proposed to identify signs of threats in the text content of social Internet services, which will allow to quickly respond to changing situations and effectively counteract such threats. A classifier of information security profiles of users of social Internet services has been developed to assess the level of their danger as potential participants in disinformation campaigns. A method for identifying and evaluating the information and psychological impact on user communities in services is proposed. Models of conflict interaction of user groups in social Internet services are considered on the example of civil movements. To effectively counter threats to information security of the state, it is proposed to use the concept of synergistic user interaction and self-organization processes in a virtual community. Particular attention is paid to countering the manipulation of public opinion in the decision-making process by users of social Internet services. The Third Section proposes a biometric security system that works to authenticate users based on a comparison of their fingerprints and certain templates stored in a biometric database. A method for determining the contour based on the passage of a curve and the filtering function of contour lines has been developed. The stage of skeletal identification is analyzed in detail. The Ateb-Gabor method with wave thinning has been developed. The performance of skeletal algorithms such as the Zhang-Suen thinning algorithm, the Hilditch algorithm, and the Ateb-Gabor method with wave decimation is analyzed. The presented results of experiments with biometric fingerprints based on the NIST Special Database 302 database showed the effectiveness of the proposed method. The software and firmware were developed using the Arduino Nano.Документ Practical implementation of the Niederreiter modified cryptocode system on truncated elliptic codes(ПП "Технологічний Центр", 2018) Yevseiev, S. P.; Tsyhanenko, O. S.; Ivanchenko, Serhii; Aleksiyev, Volodymyr; Verheles, Dmytrо; Volkov, Sergey; Korolev, Roman; Kots, Hryhorii; Milov, Oleksandr; Shmatko, O. V.On the basis of the practical implementation of the classic Niederreiter scheme for non-binary codes, a pattern has been identified for practical implementation –fixing the admissible position vectors of the plaintext transformation based on equilibrium coding. The obtained set of position vectors of the error vector with a fixed set of masking matrices (the recipient's private key) allows us to obtain the algorithm for decoding the classical Niederreiter crypto-code scheme on non-binary codes. For this, a modification of the crypto-code system (CCS) is necessary. It is proposed to use the additional parameter of key data – the initialization vector (the set of invalid position vectors of the error vector). To counter the Sidelnikov attacks, it is proposed to use modified (shortened) algebraic-geometric (elliptic) codes (MEC). For this, it is necessary to use the second additional initialization vector (the set of positions for shortening the error vector). Based on the modification of the classical Niederreiter scheme on non-binary codes, applied algorithms for generating and decrypting a cryptogram in the Niederreiter modified crypto-code system based on modified (shortened) elliptic codes and software are proposed. To confirm the profitability of the proposed crypto-code system, the results of the comparative evaluation of energy consumption for the implementation of the classical Niederreiter scheme on elliptic codes and the implementation of the proposed system on modified elliptic codes are presented. The results confirm the possibility of practical implementation of the Niederreiter crypto-code system based on the proposed algorithms. At the same time, the required level of cryptographic strength of the crypto-code system, protection of the cryptosystem against the Sidelnikov attacks and an increase in the rate of cryptographic transformations by 3-5 times compared with the classical Niederreiter scheme are guaranteed.
