摘要
光纤激光器为光纤通信提供了技术支撑,而保密性是人们进行通信的首要要求。为了满足人们对光纤通信安全性的要求,提出了混沌系统和光纤激光器的保密通信系统。首先分析了光纤激光器的工作原理以及优点,然后根据混沌系统对初始值敏感的特性,将混沌系统引入到光纤激光器的通信过程中,将通信的信号隐藏于混沌序列中,使非法者难以解码和窃取有用信号,最后通过模拟实验分析光纤激光器的保密通信性能。结果表明,该保密通信系统可以保证光纤通信的保密性,反破译性能优异,可以应用于实际保密通信中。
Fiber laser provides the technical support for the optical fiber communication, and the security should be the primary requirement of the communication. In order to satisfy the requirement of the security of the optical fiber communication, this paper proposes a secure communication system. Begins with an analysis of the fiber laser, the working principle and advantages, then according to the chaotic system to initial value sensitive characteristics, chaotic system is introduced into the fiber laser in the process of communication, hiding communication signals in the chaotic signal, the illegal users to decipher and steal useful signal, finally through the simulation experiment of fiber laser communication security performance. The results show that this system can guarantee the confidentiality of the fiber communication, and can be used in the practical secure communication.
