We propose a secure digital communication system in association with the direct spread spectrum technique. In our proposed system, the spreading signal is generated by a class of multi-dimensional chaotic maps in the transmitter and is linearly synchronized by using a drive-response coupling scheme in the receiver. Owing to the desirable statistic property of the chaotic maps and the interference reduction ability inherited from the correlation receiver, better security and considerable robustness against noise are simultaneously achieved. Theoretical analysis has been conducted and numerical experiments have been performed based on a 3-dimensional chaotic map, which illustrate our idea and verify the viability of the method.
