    • main results: Models for non-Markov SP-networks that use several different S-blocks in one round of encryption have been built, algorithms for calculating the upper bounds of differential probabilities have been refined. Criteria for the practical selection of ARX-cryptoprimitives with certain properties based on automatic stability assessment have been developed. A cryptanalysis of the new block encryption standard of Ukraine "Kalyna" and individual nodes of the block encryption standard of the Republic of Belarus STB 34.101.31-2011 "BeLT" was carried out. A modification of the cubic attack on the SIMECK cipher using information from the side channel has been performed. Estimates of the complexity of group operations for twisted elliptic Edwards curves and the feasibility of developing a new national standard of Ukraine based on Edwards curves were obtained. Four models of the attacker were built, depending on his computing capabilities, taking into account quantum computing and access to the oracle, which calculates the studied cryptographic transformation. In the post-quantum model of calculations, a criterion for an effective partial solution of the generalized symmetric decomposition problem has been developed. Formal models of the communication system and the intruder in the kleptographic sense, methods of identifying potential kleptographic mechanisms, methods of eliminating or reducing hidden channels have been developed.
