Design and implementation of a chaotic secure communication system

This paper presents a new approach to transmit and retrieve an information-bearing signal via chaotic communication system. The transmitter in the proposed communication system is using the chaotic mask circuit. This circuit uses a chaotic signal to mask the information signals. The information signals are detected at the receiver by a synchronous chaotic subsystem augmented with a nonlinear filter. SPICE simulation results and experiment are presented to verify our approach.
