对图像信息安全技术进行了研究，报告了现阶段图像加密的相关现状，分析了基于混沌理论的图像加密的主要方法，提出分别用一维混沌映射Logistic、二维混沌映射2DLogistic以及Chen超混沌映射对图像进行位置和值置乱来实现图像加密，并从实验仿真结果、密钥空间、密钥灵敏性、灰度直方图、置乱程度以及加密时间等方面来比较以上三种混沌理论作用于图像加密中的各自优缺点。

Studied the image information security technology,the report related to the status quo of the current image encryption,analyzed the main method of image encryption based on chaos theory,put forward respectively in one-dimensional chaotic map Logistic,2 dlogistic two-dimensional chaos mapping and hyperchaos mapping for the position and value of Chen to behave in such a way to realize image encryption, and from the experimental simulation results,the key space,key sensitivity,gray histogram,scrambling degree and the encryption time and so on to compare the above three kinds of chaos theory applied to image encryption in the respective advantages and disadvantages.
