To hide the fact of the transmission and storage of binary information in information and communication systems it is proposed to use complex signals, fragments of which are random processes with alpha-stable distributions and different parameters of the index of exponential stationarity characteristic. It is shown that this type of signals within the visual, time-frequency and non-linear analyses is indistinguishable from monitoring noise. An algorithm for getting a binary message into a random process and its reconstruction against the background of white noise is given. The quality of message reconstruction for various signal oise ratios at the receiver input is analyzed.
