摘要：
An all-optical encryption system which can be used in fiber WDM system and directly encrypt multi-wave optical signals is proposed. This scheme achieves multi-wave signals encrypting by the technology of generating coherently multi-wave optical plain text, Key text and the technology of phase shift interference. The feasibility and validity of this encrypting scheme are verified by simulative experiment for multi-wave signals at 8 x 10Gbps with wavelength interval of 0.8nm, the simulative result shows that when the input Pi and Ki is Gauss pulse with duty cycle of 0.3, the bit error rate and Q factor of encryption output are 0 and 164 respectively. Theory analysis and simulative experiment shows the scheme is feasible and efficient.
