摘要

In this paper, a secure image transmission method based on discrete-time chaotic maps synchronization is proposed. This method is based on designed observer in order to achieve synchronization and secure image transmission between the transmitter and the receiver. Borne & Gentina criterion was used to establish sufficient conditions for global asymptotic stability of the dynamic error between the two coupled chaotic systems, associated to the Benrejeb arrow form matrix for the system description. Simulation results are given to show the efficiency of the proposed method.
