基于混沌复合映射的语音信号流安全通信仿真实现

Simulation of Sound Signal Stream Security Communication Based on Compound Chaotic Maps

利用连续Chua’s电路方程与离散标准映射复合产生的序列,将语音信号流进行混淆并在信道中传送,该设计方案能对语音文件进行快速加密和完整还原,从密钥的敏感性及空间分析,此方案具有良好的安全保密性,适用于网络的安全传输。

Utilizing compound sequences produced by continuous Chua＇ circuit and discrete standard map, disordering sound signal stream and transmitting them in channel, this scheme can encrypt sound file rapidly and recover cipher accurately. Analyzing key space and parameters sensitivity shows this scheme is good security, and is suited to network security communication.
