Abstract

In this paper, a secure communication scheme of delayed chaotic system with channel noises is investigated. Based on the idea of chaotic cryptography, instead of encoding the message in a chaotic system signal directly, the plain signal is encrypted by using a multi-shift cipher scheme, which is more complicated and could increase the communication security. By using adaptive techniques, the transmitter and the receiver are synchronized in the presence of channel noises, and the encoded signal can be recovered by the receiver. Finally, theoretical analysis and numerical simulation show the effectiveness of the proposed scheme.
