Security-enhanced chaotic communication system based on nonlinear double-phase-perturbation encryption

Optical chaotic communication as one of the encryption communication technologies has been get a great development in recent. However, various of hacking attacks from eavesdropper are threatening security of chaotic communication system. Therefore, we propose an novel system which combined with chaotic encryption module and phase perturbation module targeting to achieve a security-enhance chaotic communication system. Simulation result demonstrate the system provide a high-security transmitting performance with on a bit rate over Gb/s and satisfactory BER is achieved.
