摘 要
为了对图像进行鲁棒的加密,在对一些规则号的2维元胞自动机进行混沌性质简单分析的基础上,计算了2维元胞自动机的分形维数,并将其运用到图像的加密和图像水印技术中。攻击实验证明了元胞自动机的混沌性质在图像加密和水印技术上的应用有较好的鲁棒性。

Abstract
The chaotic characteristics of Cellular Automata are analyzed simply and the definition of fractal dimension is constructed. Cellular Automata are applied to image encryption and image watermarking technique. The attacking examinations show that the characteristics of Cellular Automata are rather well in the application field of images.
