摘　　要：利用细胞神经网络,提出了一种基于六维细胞神经网络混沌系统的加密算法.由六维细胞神经网络构造出混沌序列,作为加密的秘钥源,根据一种无限折叠映射的混沌系统进行图像置乱,实现图像的加密.编程模拟实验仿真结果表明,加密图像与原始图像相比,直方图更加均匀,相邻像素间的相关性较小,抗攻击性较强,安全保密性较高.By studying cellular neural networks were proposed encryption algorithm based on six-dimensional cellular neural network chaotic system. By the characteristics of cellular neural networks to construct a sequence of six groups of chaos, as the encrypted secret key source, according to an infinite folding map image scrambling, realize image encryption. Finally, the simulation program simulation experiment results show that the encrypted image compared with the original image scrambling degree high correlation between adjacent pixels is small, strong anti-attack, security is high.

关 键 词：细胞神经网络 混沌系统 无限折叠映射 图像加密
