| 摘 要： | 提出了一种基于状态观测器的超混沌同步保密通信系统。用超混沌系统的多个状态量对信息信号进行复杂的加密后注入超混沌系统实现混沌调制,同时将加密后的信息信号混沌掩盖后传送出去。用状态观测器思想实现了发送系统和接收系统的同步,并在接收端将信息信号解密。由于用了超混沌系统的多个状态量对信息信号加密,增加了传输信号的复杂性,提高了通信系统的保密性。

| Abstract: | This paper presents a hyperchaotic secure communication system based on a state observer. The complex encrypted information signal is injected into the hyperchaotic system and transmitted to the receiver after chaotic masking. An observer-based approach is applied to synchronize the transmitter and the receiver. The information signal is recovered by a complex decrypter in the receiver. The utilization of hyperchaos-based cryptosystems as well as the increased complexity of the transmitted signal make a contribution to the development of communication systems with higher security. |
