In chapter four, I introduced the technology of ECC and random permutation.
第四章介绍了水印的纠错编码和随机置乱技术。
Furthermore, to enhance robustness, a random permutation of the watermark is used to defeat the attacks of signal processing, such as image crops.
另外，为了增强鲁棒性可对水印数据进行随机置乱操作以抵抗剪切等信号处理操作。
In this paper, we present a novel encryption algorithm for MPEG audio data including all three layers that is based on a random permutation scheme.
为克服目前基于混沌序列的置乱算法安全性不够高，密钥空间小的缺点，本文提出了一种新的双随机置乱算法。
