新三维混沌映射及其在数字图像信息加密中的应用
New 3D Chaotic Mapping and Its Application in Digital Image Encryption
摘要
Abstract
Based on the new 3D chaotic mapping and finite field operations,a new method of digital image encryption is constructed.Firstly,Lu mapping is used to map the original image information into two chaotic matrices.Secondly,the original image matrices and two generated chaotic matrices,are executing four rounds operations in the finite field.Exper-imental results show that the proposed encryption method can obtain uniform and fine scrambling effect.The evaluation of the histogram and three-direction correlation evaluation also has good encryption performance,and the encryption speed of the whole algorithm is also relatively fast.关键词
