PROCEDURE OF CONTINUOUS CODING OF DISCRETE INFORMATION Russian patent published in 2003 - IPC

Abstract RU 2205516 C1

FIELD: electric communication, computer engineering. SUBSTANCE: characteristic feature of procedure lies in formation of protection key in the form of binary vector with length of n bits, in its feed for initial fill of shift register generating pseudorandom sequence of maximum length, in formation of pseudorandom sequence of symbols, in conversion of data flow to encoded message and in its transmission over communication line. EFFECT: raised resistance of code to attacks based on use of known or selected texts, increased noise immunity of transmitted information. 5 cl, 2 dwg
