摘要
提出了一种基于Fibonacci变换的音频置乱方法。该方法具有变换的周期性;经一次置乱变换就可均匀分散音频信息,置乱效果好;算法速度快,能够满足实时需要,并具有较好的鲁棒性,能够抵抗一些常见攻击。
This paper presents a kind of digital audio scrambling method based on Fibonacci transformation. The transformation has periodicity. The scrambling effect is very good-the information of the audio is redistributed uniformly across the whole image after just applying one transformation. The computing speed of the algorithm is fast, so it can meet the need of real-time situations. The algorithm can resist some attacks, and the robustness of Fibonacci transformation is satisfactory.
