CHAOTIC SYNCHRONIZATION SECURE COMMUNICATIONS BASED ON THE EXTENDED CHAOTIC MAPS SWITCH
Acta Physica Sinica, 2001 A chaotic synchronization secure communication method based on chaotic maps switch is proposed. The extended chaotic model is first built to generate many kinds of chaotic signals based on changing parameters during different time durations. In the transmitter, the modulation is implemented by adding the information signal to chaotic carriers, taking a
