光电外反馈与互注入混沌保密系统研究

Chaotic secure communication system based on photoelectric external feedback&mutual injection

基于光电外反馈与互注入技术的混沌同步方法,所传同步信息较少,被截取后获得的脉冲信号恢复出混沌系统的难度极大,有效提高了保密通信的安全性。在分析光电外反馈与互注入混沌系统原理的基础上,设计了系统模型并进行了系统的仿真实验与分析。仿真结果表明,该系统具有较高的安全性和时效性。

Chaos synchronization method based on the photoelectric outside feedback and mutual injection technology, passed a small amount of synchronization information, and it is extremely difficult to recover the chaotic systems by intercepted pulse signal, it effectively improved security of the confidentiality communica- tion. So we analyzed the principle of the system, designed the system model and did system simulation and analysis. Simulation results show that the system has high security and timeliness.
