METHOD FOR STREAM ENCODING OF DIGITAL INFORMATION Russian patent published in 2005 - IPC

Abstract RU 2246179 C1

FIELD: electrical communications and computer engineering; cryptographic data conversion.

SUBSTANCE: proposed method includes generation of protection key in the form of n-bit binary vector, its supply for initial filling of shift register producing maximal-length pseudorandom character sequence, conversion of data stream into encoded message, and its transfer over communication line; in the process total character of encoded text is shaped and its value is conveyed at moment when search sequence character assumed value equal to unity.

EFFECT: reduced redundancy in message transferred and enhanced message transfer speed.
