摘要/Abstract

摘要：

针对大规模并发式保密通信对混沌阵子的需求，以Lorenz混沌阵子为例，提出了相空间对称混沌阵子群模型，研究了该对称阵子群的同步问题，得到了Lorenz阵子与对称阵子群同步的条件，利用该条件构建了基于对称混沌阵子群的通信模型并对其进行仿真验证。该对称阵子群能提供无限多个对称混沌阵子，可满足其在大规模保密通信中的应用，又能保持原混沌阵子的优良特性，具有较好的应用前景。

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.

Key words: Lorenz oscillator,, secure communication, chaos synchronization, phase-space symmetry
