摘要

研究了一种新型激光混沌编码系统。该系统将两个空间耦合激光器与另外两个激光器同步,实现了混沌保密通信中的交叉发射和交替并行接收(CEAPR)应用。理论上给出了两个CEAPR的混沌编码和解码方程;定义了激光混沌CEAPR的编码解码数学物理原则;实现了两个CEAPR技术方案的应用。系统显著特点是发射混沌编码载波的激光器和接收机激光器具有不同参数(完全不同于传统混沌通信收发同参数密钥系统),且发射源具有多个变量,可实现信息的安全交叉与交替传送,应用灵活,给入侵者从载波上破译通信内容增加了一定的难度。

Abstract

A novel laser chaotic coding system was studied herein. The proposed system realized the application of cross emission and alternate parallel reception (CEAPR) in chaotic secure communications using two space-coupled lasers synchronizing with two other lasers. We theoretically determined two chaotic coding and decoding equations of the CEAPR. In addition, the mathematical physical principle of CEAPR coding and decoding of chaotic laser was defined and described. Two practical applications of the CEAPR technology were developed herein. The proposed system characterizes different parameters between the emitter laser emitting chaotic coding carrier and the receiver laser, which is different from the traditional chaotic communication system that has the same parameter secret-keys for the emitter and receiver. The emitters have multiple-parameters and multiple-variables, can implement alternating transmission of information security, and has a flexible application. It makes it difficult for invaders to decipher the communication contents from the carrier.
