提出了一种基于广义混沌映射切换的混沌同步保密通信方式 .这种通信方式首先构建产生多种混沌序列的广义混沌映射模型 ,然后在不同时段根据切换策略产生不同混沌序列 ,在发送端 ,将信号与混沌载波之和取模运算后再嵌入混沌映射的输入端进行迭代运算以实现调制 ;在接收端 ,根据切换协议 ,用同一个相应的广义混沌映射模型从接收信号中提取混沌载波并进而恢复信息信号 .研究结果表明 :这种基于广义混沌映射切换的混沌同步通信方式比基于单一混沌系统的保密通信方式具有更强的抗干扰能力 ,保密性能更好 ,且实现简单 .
A chaos synchronization secure communication method based on generalized chaotic map switching is proposed.This communication mode first constructs a generalized chaotic mapping model that generates a variety of chaotic sequences and then generates different chaotic sequences according to switching strategies at different times.At the sending end, After the modulo operation of the signal and the chaotic carrier is modeled, the input of the chaotic map is iteratively operated to achieve the modulation. At the receiving end, the chaotic carrier is extracted from the received signal according to the handover protocol and the same corresponding generalized chaotic mapping model And the information signal is recovered.The results show that this chaos synchronization communication method based on generalized chaotic map switching has stronger anti-jamming capability than the one based on single chaotic system, and the confidentiality is better and the implementation is simple.
