EDUCATION AND TRAINING

Doctor of Technical Sciences in specialty 05.13.21 – Information Protection Systems on the topic “ MODELS AND METHODS OF INFORMATION PROTECTION IN CYBER-PHYSICAL SYSTEMS ” 
( State University of Information and Communication Technologies )
 • a concept for building a multi-circuit system for protecting cyber-physical systems has been developed, which, by integrating: a method for ensuring the confidentiality, integrity and authenticity of information resources of the software and hardware complex; a method for ensuring the closure of the mobile Internet channel and the information circulation channel, and a mathematical model taking into account the threat classifier, makes it possible to create effective information protection systems in cyber-physical systems and open a new direction in building a system for protecting information resources of the internal and external security contour of the physical platform and the management platform of cyber-physical systems.
• a method has been developed to ensure the confidentiality, integrity and authenticity of information resources of cyber-physical systems, in which, through the use of hybrid crypto-code structures with lossy codes based on the modified Niederreiter crypto-code structure on LDPC codes, it allows reducing the complexity of formation (linear transformation) and decoding in the cryptogram, ensuring the reliability of OTP passwords in the authentication protocol under the conditions of hybrid threats.
PhD in  Economical Sciences , specialty 08.00.03 − Economy and Management of the National Economy ” on the topic “PROGNOSTICATION OF DYNAMICS OF RATE OF EXCHANGE ON THE BASIS OF NONLINEAR MODELS”
• The fractal nature of the currency market of Ukraine has been proven, which determined the necessity introduction of non-linear methods in ego research (in particular, the normalized method scope, which is based on the analysis of the dynamics of the currency market itself).
• A model of the analysis of short-term trends of the currency market has been built. Given the model is based on the use of modern physical and mathematical apparatus – of spectral analysis – and construction of an autoregression model of the residuals. Its application made it possible to determine the main short-term trend of the currency market development, assume ego fluctuations and estimate the randomness of the influence of certain factors.
• A matrix model for determining the state of the foreign exchange market has been developed and highlighted four main market types: rising, falling and two combinatorial types of markets.
Master of Information Technologies programme subject area Cyber Security
(Kharkiv National University of Radio Electronics)
• Algorithms for encoding and decoding codegrams in theoretical code schemes on elliptical codes have been developed.
• Structural diagrams of devices for encoding and decoding codegrams using the proposed theoretical code schemes have been developed, practical recommendations have been made for ensuring the necessary confidentiality and reliability of data transmission in the CPS and IR.
• Special mathematical and software support for the software package of the theoretical code scheme on elliptical codes has been developed, which allows simulating the process of noise-resistant encoding and masking of information under a random sequence, and conducting experimental studies of the confidentiality and reliability of data transmission in the CPS.
