Zusammenfassung:FIELD: electric communications and computer engineering; cryptographic devices for data encryption. SUBSTANCE: method includes generation of private key in the form of combination of round sub- keys, division of data block into two sub-blocks, and execution of R>=2 encryption rounds each including transformation of first sub- block by executing sequence of operations L1,L2,...,Ln and transformation of second sub-block by executing sequence of operations H1,H2,...Hn, where n
