摘要:
引入新的三维混沌映射,结合有限域运算处理,构建一种数字图像加密方法.首先,Lu映射将原始图像信息映射为2个混沌矩阵;其次,将原始图像矩阵和生成的2个混沌矩阵,在有限域上执行4个轮次的运算处理.实验结果表明:提出的加密方法可以获得均匀细腻的置乱效果,在直方图评价、三向相关性评价等方面都表现出良好的加密性能,整个算法的加密速度也比较快.
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. Experimental 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.
