将猫映射(cat map ) 与Logist ic 映射相结合, 构造了一种语音加密算法. 该算法首先将语音数据堆叠成二维,

然后利用二维猫映射将数据的位置置乱, 最后利用一维Logist ic 映射构造替换表, 对数据进行扩散.-The cat map (cat map) and Logist ic mapping the combination of a voice encryption algorithm is constructed. The algorithm first voice data stacked into two-dimensional, and then use two-dimensional cat map the location of the data scrambling and finally the use of one-dimensional Logist ic mapping structure to replace the table, the data spread.
