提出了一种使用Tent混沌系统和Chen混沌系统相结合的音频数据加密方法,首先由Chen混沌系统产生Tent混沌系统中参数的值,然后由Tent混沌系统生成一个混沌序列作为加密因子序列,把音频数据与加密因子序列进行异或操作,实现对音频的加密。
An eneryption approach for audio data by using the combination of Tent and Chen chaotic systems is presented in this paper. The value of parameter in Tent chaotic system is generated by Chen chaotic system, a chaotic sequence is generated by Tent chaotic system. The audio encryption is carried out by a XOR operation of this chaotic sequence and the sequence corresponding to original audio.
