基于混沌映射和DNA编码的彩色图像加密算法
Color image encryption algorithm based on chaotic mapping and DNA encoding
摘要
Abstract
A color image encryption method combining deoxyribonucleic (DNA)encoding and hyperchaotic mapping is proposed to solve the problems of simple structure,low complexit and low security of the existing encryption system for low-dimensional chaotic mapping encoding system and a single DNA encoding system.Firstly,according to the information of the plaintext images,the initial values of all chaotic maps and the random matrices with the same size as the plaintext images are iteratively generated.Then,the generated initial values and random matrices are divided into the sub-blocks with the same size.The DNA encoding mode of each sub-block and the DNA operation rules between the sub-blocks are determined by the dynamic hyperchaotic sequence.Finally,the diffusion operation is adopted to achieve a better encryption effect.The simulation results indicate that the proposed encryption algorithm can resist a variety of attacks due to its high complexity,strong security and large key space.关键词
