A scheme for transmission of information masked with an irregular signal (chaotic oscillations) is considered. Mathematical models are developed for communications systems in which chaotic oscillations are radiated in two frequency bands separated owing to mixing of regular and chaotic oscillations. Results of numerical analysis and physical experiments are presented. The possibility of confidential transmission of an information signal is demonstrated.
