Research on the chaotic secure communication of the phase-space symmetric Lorenz oscillator group

Abstract

To meet the demand of chaotic oscillators for large scale secure communications,the Lorenz oscillator was taken as an example,a phase-space symmetric chaotic oscillator group model was proposed and the synchronization problem was studied.According to the condition of synchronization,a communication model based on symmetric chaotic oscillator was constructed and verified by simulation.The symmetrical oscillator group can provide an infinite number of symmetric chaotic oscillators,which can satisfy the application in large-scale secure communication and maintain the excellent characteristics of the original chaotic oscillator,and has a good application prospect.
