Abstract

The possibility of secure communication with chaos is demonstrated experimentally with two simple unidirectionally coupled electronic circuits. A traditional approach has been used to synchronize the two chaotic systems. We also study, both numerically and experimentally, the dynamic of the systems in a wide range of the control parameter. The bifurcation diagrams represent a complex behaviour whish varied from periodic orbits to chaos of the Rossler and Shilnikov types. The results of numerical simulations are in a good agreement with experiments.
