| 摘 要： | 本文在相位角θ为任意值的情况下,推出了不要帧同步的话音置乱矩阵的一种新形式。如采用这种置乱矩阵对话音加密,密钥量至少增加1倍。计算结果表明:当θ取线性相位角时,该置乱矩阵和原来的形式一致。

| Abstract: | In this paper, a general form of speech scrambling matrix which does not require frame synchronization is derived for arbitrary phase anagle 0. If a speech singnal is encrypted with the scrambling matrix, the key space size will be double at least. The results computed show that when 0 is a linear phase angle, the matrix is in accord with the original, form. |
