SECURE INFORMATION TRANSMISSION METHOD Russian patent published in 2014 - IPC H04L9/00 G06F21/60 

FIELD: radio engineering, communication.

SUBSTANCE: useful signal is encoded into a binary code; a first generator generates a source deterministic random signal by modulating parameters of the random signal with the useful digital signal and the obtained signal is transmitted over a communication channel to a receiving side where it is divided into two identical signals which are transmitted to a second generator and a third generator, which are identical with respect to control parameters, selected to facilitate a mode for general synchronisation with the first generator; signals obtained from the outputs of said first and third generators are transmitted to a subtractor and presence or absence of oscillations determines presence of a useful digital signal presented in form of a digital code, wherein periodic signals are obtained at the outputs of the second and third generators.

EFFECT: improved stability of the method.
