| 摘 要： | 提出了一种新的基于超混沌序列的数字图像加密算法.首先应用Hyperhenon映射产生混沌序列,用此混沌序列对图像做预处理加密;接着应用Kawakami映射产生的混沌序列,对预处理后图像的行和列分别做改进的魔方置乱,最后应用评价指标对加密效果和安全性进行分析.实验结果表明,该方法具有较高的安全性以及加密效率.

| Abstract: | An improved image encryption method is proposed based on chaotic sequence and image encryption technology. Firstly, chaotic sequences are generated based on Hyperhenon and applied to pre-encrypt the image; then further processing are used for retreated the image, including renew magic-cube scrambling based on Kawakami mapping. The effect of encryption is also analyzed by using the method of accessing. Simulation results indicate that the method has good efficiency and security characteristic. |
