| 摘 要： | 混沌序列具有易生成性，对初始条件强敏感性，可完全重现性等特点，基于以上特性提出了一种基于混沌序列的图像置乱加密算法，以初始条件为密钥生成混沌序列，然后依据该序列随机修改图像中每一个象素点的RGB值，同时采用基于DES的双向异或置乱算法对图像进行置乱．模拟实验证明该算法实现简单，计算量小，且图像的解密结果对混沌序列的初始值有较强的依赖性，安全性高．

| Abstract: | Chaotic sequences have several good properties, such as the ease of the generation, their sensitive dependence on its initial parameters. Because of these good properties, chaotic system can be used to image encryption. In the paper, an image encryption algorithm is proposed based on chaotic sequences and image scrambling. As the initial parameter is the key, the chaotic sequences can be generated based on key. Then according to discrete sequences, the RGB value of pixel is modified randomly. Two directions XOR scrambling algorithm based on DES is used to scramble the image. Simulation results prove the algorithm possesses the feature of low computational complexity, dependence on its initial parameters and high security. |
