【Abstract】 In this paper, a chaotic dual-directional secure communications scheme of external lightinjected semiconductor lasers is presented. Chaos analog secure communication with a sinusoidal signalof 0.2GHz modulation frequency, chaos digital secure communication with a digital signal of 0.1bit/smodulation rate and chaos shift keying secure communication with rate 0.025bit/s are numericallysimulated, respectively. The decoding character and the modulation bandwidth of the system areanalyzed, in particular.更多还原
