Study of the Effects of Chaos Attacking on Optical Fiber Communication Systems

摘要

We study the effects of chaos attacking on optical fiber communication systems. We analysis the effects of chaos masking interference (CMI) and chaos phase interference (CPI). In CMI, the larger chaotic signal can mask fully the message signal and the smaller chaotic signal can also interfere the message signal by the state superposition-couple principle. In CPI, the characteristics of the chaotic signal can overprint the phase of the message signal by the cross-phase modulation so that chaos can interfere the message signal. At last, optical fiber communication systems with bit rates of 2.5 Gbit/s, 5 Gbit/s and 25 Gbit/s are simulated in CMI and CPI, respectively, to find that chaos can interfere effectively optical fiber communication systems.
