摘　　要：介绍混沌系统以及二维Henon映射,针对RGB彩色图像的特点,给出一种新的基于Henon映射的RGB彩色图像加密方案。利用Henon映射的特性,对RGB彩色图像每个通道分别生成不同的密钥和混沌序列进行像素点移位和异或加密,该算法相对一维混沌映射加密算法更为复杂,破译难度更大。实验结果表明,该算法易于实现,能达到良好的加密效果,并能在一定程度上抵抗统计分析攻击、剪切攻击,具有良好的抗攻击性。Introduces chaotic system and two-dimensional Henon mapping,and presents a new RGB color image encryption scheme based on Henon mapping for the characteristics of RGB color images.By using the characteristic of Henon mapping,each channel of RGB color image gen?erates different key and chaotic sequences for pixel shift and XOR,which is more complicated than one-dimensional chaotic map encryp?tion algorithm,and it is more difficult to decipher.The experimental results show that this algorithm is easy to implement,can achieve good encryption effect,and can resist statistical analysis attack,shearing attack to some extent,and has good anti attack ability.
