FIELD: electric communications engineering and computer science.
SUBSTANCE: method includes generation of encryption key in form of binary vector n bit long, sending aforementioned vector for primary filling of shift register with check connection, having n digits, forming of pseudo-random series of symbols of terminal field Fp with characteristic p=257 in form of binary vectors, generation in form of binary vectors of symbols of sorting series due to powering parent element in terminal field Fp, splitting data stream on block-symbols of source text ion form of binary vectors 8 bit long, generation of summed symbol of source text in form of binary vector by adding in terminal field Fp of symbol of source text with all previous symbols of source text and serial transformation of binary vectors of source text symbols by multiplication of them by symbols of sorting series and adding in terminal field Fp of received result with symbols of pseudo-random series, replacement of parent element of sorting series during appearance of symbol "1" in its composition by summed symbol of source text, encoding of new parent element, transformation of data stream of source text into encoded text and transfer of encoded text and new parent element via communication line. Method is distinguished by generation of summed symbol of encoded text in form of binary vector by adding in terminal field Fp of next symbol of encoded text with to all previous symbols of encoded text and transfer of summed symbol of encoded text along communication line after replacement and transmission of parent element of sorting series.
EFFECT: increased resistance to interference for transferred information.
