基于五维超混沌的全球信息栅格图像加密算法
Image Encryption Algorithm Based on Five-Dimension Hyperchaotic System for Global Information Grid
摘要
Abstract
A new image encryption algorithm based on five-dimension hyperchaotic system was presented to solve the issues of network data security for global information grid. The image encryption scheme based on hyperchaotic system for the communication system of global information grid was given. Two chaotic sequences were preprocessed to shuffle the positions of image pixel, and a chaotic sequence was selected and preprocessed for pixel value encryption of image to change the gray values. Simulation results and analysis show that the proposed encryption algorithm has the advantages of large key space, key selection sensitivity, high security and good encryption effect.关键词
