Krulova V. Development of standardized methods for the protection of information in computer-integrated systems

The object of research is the process of processing, protection and transfer of information in specialized computerized systems and networks management objects. Objective: to develop and improve the unified methods and algorithms to protect information from errors in computerized integrated systems that provide high reliability and speed. Methods: methods of the theory of processing and transmission of information, theory of error-correcting coding of information in digital systems, the mathematical apparatus of information theory and stochastic processes, linear algebra, probability theory, methods, Fourier analysis and synthesis of linear algebra, mathematical statistics. Theoretical and practical results: adaptive coding methods have been developed with variable parameters, which are implemented in hardware and software data protection and transmission of information on modern FPGA dynamically reconfigurable type FPGA, and provide high reliability and speed of data transmission in computer-integrated systems. Scientific novelty: first proposed and developed a method for adaptive correction code parameters based on generating a plurality of nested coagulation codes with different energy gain at the expense of coding that allows the synthesis of a unified information security algorithms in computerized systems; developed a method for determining the quality of the information channel based on an assessment of the statistical characteristics of error stream that allows you to change the current state of the information channel to optimize the parameters of the code in order to maximize the transmission rate with a minimum redundancy code; proposed and developed a method for the formation and consolidation of wideband signals to provide accurate and timely communication of information in computerized networks and improve their energy efficiency and noise immunity. Implementation: results are implemented at the state enterprise "Kharkiv Machine Building Design Bureau named. Morozov," National Technical University "KPI" (Kharkiv). Areas of use: designing or upgrading systems for the protection of information in computer-integrated systems, the learning process.
