Methods and means for the automatic dynamic scientific and educational resources ordering of the global electronic information environment

In the process of work was implemented fundamentally new software architecture ащк automatic systematization of scientific and educational segment of the global electronic information environment. Scientific and educational orientation allows using the features of the relevant data, especially the fact that they can usually be classified as semi-structured. This leads to the possibility of using structured methods aimed at processing the class, including methods based on Information Extraction.

Development of digital modem equipment for next generation tropospheric stations and small satellite radio communication systems

The structural and functional principles of modem equipment construction for over-the-horizon communication were developed. Time adaptation algorithms for changing conditions of over-the-horizon communication station, based on fuzzy conclusion algorithms were developed. Algorithms of frequency adaptation for initialization and continuous operation modes were developed. Algorithms to receive energy estimations of the channel and their statistical parameters were developed.

Research and application methods of cryptanalysis of unilateral cryptographic transformations in classical and quantum computing model.

Cryptanalytical methods of one-way mappings are modified and developed in classical and quantum computational model. New statistical criteria are proposed for evaluation of random and pseudorandom generators’ quality. Security evaluation methods against differential and linear cryptanalysis are developed for non-Markov symmetric block ciphers with their structural specific taken into consideration. Upper bounds of average probabilities of integral differentials are estimated for some classes of mappings.

The development of the combined system to provide the safety and survivability complex technical system functioning in real time

There are proposed the methodological, mathematical and algorithmic toolkit for the integrated system to ensure the security and survivability (ISSS) of complex technical systems (CES) functioning in real time based on the timely formation and implementation of decisions and unremovable threshold time limit for cycle control in abnormal conditions.

Investigation of novel ultrawideband adaptive low-profile antenna arrays for future radioelectronic systems for dual applications

Novel method and technology of planar scanning ultrawideband antenna arrays for L-,S-, C- bands were developed. Attractive features of the arrays are wide angle scanning sector (up to ±45° in orthogonal planes), low level of cross-polar radiation, low active reflection losses (
