基于混沌复合映射的语音文件的分组加密实现

The realization of sound file grouping encryption based on compound chaotic maps

利用混沌映射产生的轨道点的遍历性及初始值的敏感性等特点,采用Logistic映射产生的序列和baker,cat混沌映射作为分组置乱算法,设计了一种对WAVE语音文件进行加密的方案。用VC++仿真模拟结果表明,这种混沌分组密码置换语音文件具有复杂性高、保密性好等优点。

Utilizing the specialities of throughout trajectory and initial sensitivity produced by chaotic maps,adopting Logistic series and baker,cat chaotic as maps grouping diffusion algorithm,this paper designed a scheme encrypting WAVE files, simulation results indicate that this scheme has highcomplexity and good security.
