| 摘 要： | 介绍了DES加密算法的基本特点，分析了DES的加密实质，并且结合图像数据的行列变换特性，提出了基于图像特性和DES的快速图像加密解密算法。该算法首先对图像进行行列变换，然后进行小部分图像数据的正常DES加密，对大部分图像数据进行DES异或运算，得到加密图像。实验结果表明此算法具有较好的安全性、高效性，且易于实现。

| Abstract: | The basic characteristics and the essence of DES are introduced and analysed. A new method of fast image encryption based on image characteristics and DES is presented. Firstly, image transform is conducted based on rol and col. Then a part of image is encrypted by DES. Most of the image data are encrypted using DES XOR operation. Experimental results show that this method has better safety , efficiency and is easy to be realized. |
