摘要
通过对音频信号高采样率采样过程中实时加密的研究,提出了一种结合异或运算和循环移位操作的双重置乱混沌加密算法,对高采样率音频信号进行加密和信息掩盖.加密序列和循环移位序列均由混沌系统产生,整个过程在数字信号处理器(DSP)平台进行了验证.此方法运算速度快,安全性高,易于在嵌入式系统中进行应用.
This paper proposes a kind of algorithm which combination of XOR and cyclic shift,a dual-scrambling chaotic encryption via researching the real-time encrypt in the process of audio signal high rate sampling,to encrypt and cover the information of high sampling rate audio signal.Encryption sequence and cyclic shift sequence are generated by chaotic system;the whole process was verified in the digital signal processor（DSP） platform.This method is computing speed and high security,so it can be easily used in embedded systems.
