基于EMD的数字图像混沌加密算法
Digital Image Chaotic Encryption Algorithm Based on EMD
摘要
Abstract
High dimensional chaos system is one important technology for digital image encryption.However,the higher the dimension of chaos system is,the more complex the algorithm is.In order to solve the problem,a new digital image encryption algorithm based on empirical mode decomposition (EMD) is proposed.The original digital image is decomposed into several digital matrices by EMD algorithm.After preprocessing,the corresponding digital images are obtained,and the correlation between adjacent pixels is also destroyed.On the other hand,the obtained images are encrypted by applying chaos system.Each image can be encrypted by the same chaos system with different initial value,or by the different chaos system.Finally,the encryption effect of this algorithm is illustrated by numerical experiments.关键词
