GUI Orthogonal Latin Square+2-D Arnold Scrambled Image Encryption 1. Introduction 1 Purpose of digital image scrambling Up to now, more mature information hiding algorithms are basically based on images as carriers. Image scrambling, as the name implies, is to scramble the image to hide the real content of the original image. Digital image ...

preface The previous article introduced the basic knowledge of chaos, including three classical chaotic maps and Hodgkin Huxley model. This paper will introduce text encryption based on chaotic mapping. This chapter first introduces the cryptosystem based on the traditional DES algorithm and the typical text cryptosystem based on chao ...

Algorithm overview The programming language used in this program is C#. C #'s Aforge.imaging library was initially used. After many debugging and algorithm function analysis, it is found that there are great problems in the implementation of FFT in the library. It can only transform the picture Fourier, but not the inverse transform. And ...
