Abstract

The paper give our study of a hyperchaotic synchronization erbium-doped fiber laser secure communication system with dual-channel secure transmission performance, its encoding and decoding. First, we present a signal transmission synchronization scheme, where a signal from one of a hyperchaotic erbium-doped fiber three-ring laser as an emitter transmits to an erbium-doped fiber dual-ring laser as a receiver while the emitter can synchronize with the receiver by anti-phase control technique. Second, we give an encoded signal secure transmission scheme, where two signals from two ring of a hyperchaotic erbium-doped fiber three-ring laser mask two information signals, respectively, transmit to two terminals of the receiver with an erbium-doped fiber dual-ring laser to perform two encoded signal secure transmissions in two channels. Third, we give a decoding scheme, where two carrier signals from two channels subtract two signals from two ring of an erbium-doped fiber dual-ring laser to result in decoding realizing. Then, such hyperchaotic encoding secure communication laser system can perform on dual-channel secure encoding transmission and enhance the security of classified information signals. Our numerical result indicates that the hyperchaotic secure communication laser system can perform on dual-channel secure encoding transmission, and succeed decoding in dual-channel. The hyperchaotic secure communication laser system has an important reference for people’s study of optics chaos secure communication, multi-channel secure transmission, encoding and decoding.
