Design and Implementation of Image Encryption System Based on Random Grids and Mscan Patterns

摘要

In the field of information security and the rapid development of network technology and the era of Internet+,the concept of cyberspace security has risen,and related algorithms and related works for image encryption have emerged.This paper studies the image encryption based on the random grid encryption algorithm and the modified SCAN encryption algorithm.A hybrid image encryption system is proposed and designed by combining these two algorithms.This also considered the distortion,compressibility and encryption strength of the image.Using the defects of the MSCAN algorithm,a simulation attack was performed on the traditional MSCAN encryption algorithm.Finally,statistical analysis and diffusivity tests are used to evaluate the design of the encryption system.
