The object is processes of cryptographic information transformation using block symmetric ciphers; aims - to develop methods of forming random type S-boxes with improved security properties; methods of probability theory, mathematic statistics, combinatorics; news - first time were developed new methods of forming S-boxes considering cryptographic properties of strenght against differencial and linear cryptoanalysis; the results - new methods of substitution selection were proposed, that allow to improve security properties of ciphers; all ties thesis has been used in activity of "IIT" and education process of KHNURE; the field - Information Security Systems.
