FIELD: physics; communication.
SUBSTANCE: invention relates to radio engineering and communications theory and can be used in communication systems which use random carrier signals for protecting transmitted information. The method for multichannel confidential information transmission involves modulation of parametres of a random oscillation generator in a transmitting device using several information analogue signals, transmission of the signal from the random oscillation generator over a communication channel to a receiving device, detection of information signals. Before detection, the analogue signal is converted to digital. During detection, current values of parametres of the random signal generator which correspond to transmitted information signals are determined using reconstruction dynamic system methods and discrete wavelet analysis.
EFFECT: high level of information security.
