Zusammenfassung:FIELD: communication, computer engineering, in particular, cryptography. SUBSTANCE: method involves generation of secret key, splitting data records into N blocks, and sequential conversion of blocks by running at least one conversion for i-th block, depending on value of j-th block, where j is not equal to i. In addition after generation of secret key method involves generation of encryption algorithm depending on value of secret key by running at least one conversion operation over i-th block. Said conversion operation is designed as substitution. EFFECT: increased resistance to known methods of cryptanalysis, including differential and linear cryptanalysis. 2 cl, 3 dwg
