Abstract: Using a multi-scroll oscillator with an adjustable number of scrolls as chaos generator, this paper shows how an adequate control of the chaotic masking signal provides the basis for an improved security in private communication. We base the selection of the masking signal on two criteria related, respectively, to the energy and the spectral location of the signals in the complex synchronization network. The result is a successful encryption, transmission and retrieval of a confidential message in a two-channel communication system with multi-user modality.
