METHOD FOR STREAM ENCODING OF DISCONTINUOUS INFORMATION Russian patent published in 2007 - IPC H04H9/00 

FIELD: electric communications and computer engineering, area of methods and devices for cryptographic transformation of data.

SUBSTANCE: method includes generation of protection key, sending thereof for beginning filling of shift register, producing pseudo-random series of maximal length, generation of pseudo-random series of symbols, transformation of data stream to encoded message by involution of symbols of source text to power, appropriate for symbols of pseudo-random series, and transfer of encoded message via communication line. In current method, pseudo-random series is formed as pseudo-random series of symbols in form of binary vectors k bit long, while cryptographic transformations are performed in the circle of residue classes with modulus p=2^k.

EFFECT: increased speed of data encoding and expanded range of alternation of resistance of code to attacks on basis of known or matched original texts.
