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.
