摘要 为了实现稳定的、可以同时同步的多点混沌通信,提出一种基于光电反馈延迟的双向混沌通信模型和多点耦合的混沌同步模型。在双向混沌通信模型中引入了时间延迟和混沌调制信息加密技术,增加了系统的安全性。数值分析了系统的同步性能、安全性能和通信性能,研究结果表明,系统能够历经很短的时间实现高质量的、稳定的同时同步,实现双向通信。并且延迟时间、信息信号功率、激光器光信号功率、相位的改变在其他参数匹配的情况下,不会降低系统的同步性能,即系统的信息信号功率、光信号功率、延迟时间、相位均可作为系统的密钥,提高系统的安全性。这种双向混沌通信模型可以拓展为符合一定拓扑结构的多点耦合混沌通信模型,并且推测随着网络中节点数的增加,系统的复杂度增加。 In order to achieve a stable, isochronous and synchronous multi-coupled chaos communication, a bidirectional chaos communication system and a multi-coupled chaos synchronization model using optoelectronic feedback delay are proposed. The time delay and chaos modulation encryption technology are introduced to increase the security of the system. The synchronization characteristics, safety performances and communication performances of the system are numerically analyzed. The results show that the stable isochronous synchronization can be observed after a very short time. What′s more, the changes of the delay time, powers of information signals, powers of laser optical signals and phases have not bad influences on the system qualities, namely these parameters can be used as keys to improve the security of the system. The proposed bidirectional communication system can be extended to a multi-coupled communication system which meets a certain topological structure, and we speculate that with the increase of the dots in network, the complexity of the system increases.
