DFT
自己实现的一维、二维DFT。优点：变换后的低频分量在中间，弥补了matlab库函数的不足（高频分量在中间）(Realize their own one-dimensional, two-dimensional DFT. Advantages: low-frequency components after the transformation in the middle, made up for the inadequacy of matlab library function (high-frequency component in the middle))

vigenere
vigenere密码在起初的破译中是靠穷举法，找出与阅读习惯最适合的明文，但是也可以先缩小穷举范围，再查找(vigenere initial crack passwords by brute-force method is to identify the most suitable and clear reading habits, but can also be reduced exhaustive range, and then find)

HEU_KMSActtivator
说明： 本文提出了一种基于混沌加密的DCT域二值图像数字水印算法.该算法首先利用混沌序列将含有版权信息的有意义二值图像水印进行加密,然后利用人眼视觉系统(HVS)的特性将原始载体图像进行块分类,最后将不同强度的水印分量嵌入到不同类的图像块DCT中频系数中去.利用混沌序列对水印进行加密,使水印本身具有安全性,对数字作品进行双重保障.通过高斯噪声,椒盐噪声以及JPEG压缩和剪切等攻击试验,表明了该算法具有较好的鲁棒性.(Encryption in DCT domain is proposed. Firstly, the meaningful binary image watermark containing copyright information is encrypted by using chaotic sequence, and then the original image is classified by using the characteristics of human visual system (HVS), Finally, the watermark components with different intensities are embedded into the DCT intermediate frequency coefficients of different types of image blocks. Chaotic sequences are used to encrypt the watermark, so that the watermark itself has security and double protection for digital works. Experiments on Gaussian noise, salt and pepper noise, JPEG compression and clipping show that the algorithm has good robustness)
