| 摘 要： | 混沌序列具有易生成性，并且具有对初始条件强敏感性、伪随机性、可完全重现性等，基于以上特性提出一种基于混沌序列的图像置乱加密算法，即首先以初始条件为密钥生成混沌序列，然后依据该序列进行图像置乱。软件模拟实验证明该算法实现简单，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: | The chaotic sequence is easy to build,and has strong sensitivity to initial conditions,pseudo - randomness, can completely reproduce and so on. Based on the above characteristics of this issue, the author presents a chaotic sequence based on image scrambling encryption algorithm, first of all to the initial conditions for the key generation chaotic sequence, and then based on the sequence of image scrambling. Software simulation experiments show that the algorithm is simple and the image of the decryption results of the initial value of chaotic sequences have a stronger dependence on high security. |
