Abstract
En 中文
This paper proposes a multi-channel parallel mode shift keying secure communication scheme based on multi-mode chaotic laser synchronization, aiming to address the issues of structural complexity and low transmission rates in traditional chaos shift keying (CSK) systems. By leveraging the multi-mode characteristics of a Fabry-Perot (FP) laser, the system maps binary information onto chaotic attractors of different longitudinal modes, enabling parallel multi-channel information keying. Combined with wavelength division multiplexing (WDM) technology, the transmission rate is significantly enhanced. A dual encryption mechanism is implemented by firstly performing chaos shift keying encryption on each channel independently, followed by collective encryption of the multiplexed signal through chaotic phase modulation, effectively concealing wavelength information and improving anti-eavesdropping capability. Simulation results demonstrate that the system achieves secure transmission at an aggregate rate of 30 Gb/s over a span of 80 km single-mode fiber, exhibits strong resistance to return map attacks, and possesses excellent security and practicality.
