FIELD: computer engineering.SUBSTANCE: group of inventions relates to computer engineering and can be used in devices of data protection. Method includes steps of setting length W of the computer system processor equal to an integer degree of number 2, setting available memory volume of the computer system M bits, setting size s of message S, herewith s is multiple of W, setting capacity value n of a linear feedback shift register (LFSR) as per Galois, forming the LFSR as per Galois, modifying the LFSR, performing R cycles of the modified LFSR operation, calculating output state of the modified LFSR cells, obtaining after R cycles of the LFSR operation a linear conversion of s blocks of message S, reading from the modified LFSR cells s blocks of the linearly converted message S, combining the blocks and receiving the linearly converted message S.EFFECT: technical result is reduced memory volume at the specified capacity of the processors.2 cl, 14 dwg, 3 tbl |
