| 摘 要： | 对Lorenz序列进行了改进，改进后的序列具有理想的伪随机特性。提出了应用改进后的Lorenz序列进行图像加密的算法，该算法对图像的像素和空间位置均进行置乱。仿真及分析结果表明，该算法密钥空间大，具有较好的统计特性、较强的抗干扰能力和较高的执行效率，加密效果对密钥敏感。

| Abstract: | Lorenz sequences were improved to be with ideal pseudo-randomness. An image encryption algorithm was proposed, which scrambled the pixels and the spaces of the image with the improved Lorenz sequences, The simulation and analysis show that the algorithm has a large space of keys, good statistical characteristics, strong anti-noise ability and high efficiency, and the encryption effect is greatly sensitive to the keys. |
