“…Formulation of the problem. In software systems, the term «self-healing» implies the presence of any application, service or system that can detect that it is not working properly, and without any human intervention to make the necessary changes to restore itself to normal or design condition [18,20,23]. The same actions can be performed by the system in case of probable failure of its structural elements [5,19,26].…”

Given recent events, training during quarantine can only take place remotely. To ensure quality training, communication must be seamless. To do this, the network must function smoothly. The solution to this problem is functionally stable networks that allow uninterrupted transmission of information due to redundancy. An important issue is the definition of redundancy. To solve this problem, the article considers the method of synthesis of the structure of the distance learning system. The method of synthesis of network structure used for providing distance learning by the criterion of maximum functional stability on the basis of the introduction of correcting communication lines is offered. With this method, you can develop tools for self-recovery of distributed software, taking into account the characteristics of disparate computer resources through the use of redundancy. This will allow you to develop functionally stable software systems, significantly reduce the recovery time of such systems after or in the event of possible failures. To increase the efficiency of the developed method, the mathematical model of the hyper network based on two hypergraphs was improved, which allows taking into account different requirements for the quality of the network.

“…Thus, a channel is called hidden if it was not specifically designed and was not originally designed to transmit information in an electronic data processing system, such channels include digital steganography algorithms in spatial and frequency domains based on the impossibility ("weakness" of perception of information as visual system and the human auditory system). Such a container can be images (images, videos), audio and text files [11][12][13][14].. Crypto-infrastructure with a loophole (Backdoor, Trapdoor) is an algorithm that contains some hidden structure (loophole) that ensures the existence of a hidden channel of information transmission; knowledge of this structure allows you to get secret information (for example, about the secret key). Without knowledge of the loophole, the algorithm seems reliable.…”

The entry of mankind into the era of high technology, the rapid growth of computing technology contributes to the expansion of the range of electronic services. To ensure the security of sensitive information, personal data is used cryptographic systems of traditional cryptography (symmetrical cryptosystems) and cryptography with open keys (asymmetric cryptosystems). As a rule, the first provide security services, the second -the distribution of keys. However, in the conditions of totalitarian surveillance in society by the special services of developed countries in cryptographic algorithms "embedded" cryptographic bookmarks, which on the one hand provide "fast" access of special services to confidential information, on the other hand, allow attackers to hack into the cryptosystem and get user data. The article proposes a modification of the wellknown algorithm (OFM) S-box, which provides "elimination" of possible cryptographic bookmarks and increasing crypto resistance in the post-quantum period (the appearance of a full-scale quantum computer, that allows you to hack on the basis of The Grover and Shore algorithms modern symmetrical and asymmetrical cryptosystems). In addition, commercial implementation will ensure the "opposition" of possible crypto-deposits by the special services, that will reduce the risk of hacking by identifying "weak" (vulnerable) places based on cryptographic bookmarks.

“…The need for effective intelligence and combat operations in the East of Ukraine contributes to the active introduction of advanced technologies in the development of aviation [1][2][3]. The level of flight safety and the ability to perform a set task are determined by many characteristics [4][5][6][7]. The wide variety of situations that arise in thecourse of control procedure, and the need for prompt adoption of decisions compliant with various quality requirements, necessitate the comprehensive use of a rich armory of mathematical models and methods [8][9][10][11].…”

This work considers the methods of optimal linear extrapolation of the flight path of the aircraft, which provide a minimum of the mean square of the forecast error with different amounts of a priori information. The research is based on the canonical decomposition of a vectorial random process. It is determined that the development of modern technologies entails increasing requirements for quality and accuracy of control. However, since the existing methods of linear extrapolation do not provide for the maximum accuracy of the forecast due to the inherent constraints on the random process that describe the motion of aircraft, this necessitates a further development and improvement of methods for extrapolation of aircraft trajectories. The peculiarity of the developed methods for extrapolation of aircraft trajectory is that they allow within the correlation model to fully take into account the properties of a real random process that describes the motion of aircraft at the landing approach stage. This provides for the maximum possible accuracy of linear extrapolation with a variety of information support conditions. These methods allow improving the safety of flights and the efficiency of aviation. Accordingly, new capabilities of aircraft and other sophisticated technical systems can be further considered.
