Secure communication via multiple parameter modulation in a delayed chaotic system

Abstract

The problem of secure communication via parameter modulation in a chaotic system is considered. Information signals are used to modulate various parameters of a chaotic system. The resulting chaotic signal is later demodulated and the information signals are recovered using an adaptive demodulator. The convergence of the demodulator is established and simulation results validate the theoretical predictions. (C) 2004 Elsevier Ltd. All rights reserved.
