| 摘 要： | 图像置乱变换是信息隐藏和图像加密的常用方法。但传统的图像置乱都具有一定的规律性，再加上置乱具有周期性，很容易被攻击者击破。本文是在混沌调制的基础上再进行双重置乱，取得了良好的置乱效果，且增强了可靠性和保密性，仿真结果和试验表明：密文加密效果好，恢复图像与原图像一致。此算法对密钥敏感，具有很好的抗干扰能力，同时在数字水印的预处理中对水印的置乱有着一定的应用潜力。

| Abstract: | Image scrambling transformation is a common method in information hiding and image encryption.However,the traditional image scrambling has certain regularity and periodicity and can easily be broken by the attacker.In this paper,the image are dual scrambled based on chaos modulation,the result has a very good scrambling effect and enhances the reliability and confidentiality.The final results of the simulation tests show that the effect of encryption is good and the original image and the restored image is ... |
