A Unique chaotic image encryption on the basis of Enhanced Thorp shuffle and Zig-zag Scan based Convolution (ETS-ZSC) is proposed in this paper. A one-dimensional chaotic map is utilized for both shuffling the plain image and producing the critical grid for the convolution activity. The substitution operation is performed in two ways: forward substitution and reverse substitution with zigzag scan. The original seed of the logistic map is created from the hyper chaotic system by matching with the plain image to overcome the differential attacks. The security analyzes are held for the proposed method to prove safe against the chosen plain text/known plain text attack. From the simulations results, it is observed that the proposed methodology is having enough high key sensitivity, key space, good randomness, and equal sharing of pixels in cipher image.

本文提出了一种基于增强型 Thorp shuffle 和 Zig-zag Scan based Convolution (ETS-ZSC) 的独特混沌图像加密方法。一维混沌图用于对普通图像进行混洗并为卷积活动生成关键网格。代换操作有两种方式：正向代换和锯齿形扫描的反向代换。逻辑图的原始种子是从超混沌系统中通过与普通图像匹配来克服差分攻击而创建的。对所提出的方法进行安全分析，以证明对所选纯文本/已知纯文本攻击是安全的。从仿真结果可以看出，所提出的方法具有足够高的密钥灵敏度、密钥空间、良好的随机性、
