RK龙格库塔定理产生密钥图像简单加密和恢复,简单的异或运算(Simple encryption and recovery of RK key image)

图像经过双随机处理和分数阶傅里叶变换，可以达到加密解密的功能，且对密钥敏感性较强。(The image undergoes double random processing and fractional Fourier transform, which can achieve the function of encryption and decryption, and has strong sensitivity to the key.)

通过级联分数傅里叶变对图像进行加密解密，可自行设置秘钥，以及加密的阶数，具有良好的保密性(Encryption and decryption of image by fractional Fourier transform)

简单的混沌加密，在网易云课堂听课，做的笔记，简单的几个混沌加密，数字水印混沌加密，混沌加密生成二值图像、灰度图像、RGB图像(Simple chaos encryption, in the netease cloud class, take notes, a few simple chaos encryption, digital watermark chaos encryption, chaos encryption generated binary image, gray image, RG
