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.

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 (<0,3 for the absolute majority of array elements) in ultrawide frequency band with coverage up to 7:1. In addition developed antenna arrays are characterized by high efficiency (up to 95%) in L-,S-,C-bands, low weight (less than 15 kg/m2) and low profile (<λmax/10).

Computer aided design tool development and their use for the high-speed vision processor design

Computer aided design tool development  and their use for the high-speed vision processor design

The vision system for the high dynamic range (HDR) video signals is developed. The system performs the HDR image compression to the signal with dynamic range of 48 dB without loss of sharpness in the light and dark areas and no artifacts, and has moderate hardware costs when it is implemented in FPGA. The Retinex compression algorithm based on the bilateral function is considered. A simplified HDR compression algorithm is proposed, that uses the intelligent image analysis of local characteristics instead of the bilateral function .
