The article focuses on the possibility to reach the required values of noise immunity, communication system security on the basis of realization of dynamic mode functioning in communication systems whereby change of message bit correspondence – complex signal by the law, the prediction of which is possible with a probability not exceeding the limits. Necessary and sufficient conditions of absolutely secure system construction on the level of signal source were formulated.
complex signal, dynamic mode, noise immunity, secrecy
