摘　　要： 提出了一种使用多个混沌系统相结合进行彩色图像加密的方法,由Logistic系统产生Henon混沌系统的参数值,之后把由Henon系统生成的混沌序列作为加密因子序列;把图像的像素所对应的二进制序列与加密因子序列进行异或运算,从而得到加密后的图像。 The chaotic system is a complex nonlinear dynamic system with pseudo randomness and uncertainties, as well as the initial condi- tions and the extreme sensitivity of system parameters. The chaotic sequence produced by chaotic system is very suitable for information encryption such as text and digital images. An encryption method for color images based on Logistic and Henon chaotic systems is presented in this paper. The chaotic sequence is produced by the Logistic and Henon systems. The image encryption is performed by the XOR operation of the sequence corresponding to original image and the chaotic sequence.
