We propose a secure algorithm for direct encryption and decryption of digital images with chaotic map lattices. The basic idea is to convert, pixel by pixel, the image color to chaotic logistic maps one-way coupled by initial conditions. After small numbers of iterations and cycles, the image becomes indistinguishable due to inherent properties of chaotic systems. Since the maps are coupled, the image can be completely recovered by the decryption algorithm if map parameters, number of iterations, number of cycles, and the image size are exactly known.
我们提出了一种使用混沌映射晶格对数字图像进行直接加密和解密的安全算法。其基本思想是逐像素地将图像颜色转换为由初始条件单向耦合的混沌逻辑映射。经过少量的迭代和循环后，由于混沌系统的固有特性，图像变得难以区分。由于映射是耦合的，如果映射参数、迭代次数、循环次数和图像大小确切已知，那么图像可以通过解密算法完全恢复。
