Abstract

A secure communication scheme using a chaotic system is presented. The noise-like properties of chaotic signals has been exploited previously for secure communications. However, because previous methods require very high signal-to-noise ratio (SNR) and/or the self-synchronization property of the chaotic system, their application to practical secure communication systems is limited. The proposed scheme in this paper uses a noise reduction method which has exhibited good performance for reducing the dynamical error. It determines which data stream comes from the particular system by comparing the power level of the dynamical error of each data stream. The advantages of the proposed system are that it requires no synchronization of the receiver to the transmitter and it is robust to channel noise
