Abstract Chaos theory is initially developed in the 1970s and has been utilized in the field of cryptography for the last three decades. In present work, an implementation of image encryption technique using chaotic system, compression and S-boxes is discussed. In this encryption scheme, compression is used to hide the original size of (plain text) image and also reduce the time complexity of the scheme. In addition to this, a particular S-box is selected for the encryption process with the help of an improved range chaotic map. The proposed scheme is discussed in detail, along with its standard security analysis and experimental results. This improved chaotic map and S-boxes provide large key space and high level of security. The size of cipher text generated by this scheme is different from plain text and is easy to implement for practical application of secure transmission of confidential data.

利用压缩、动态系统和 S 盒的先进图像加密技术

摘要 混沌理论最初是在 1970 年代发展起来的，在过去的三年中一直被用于密码学领域。在目前的工作中，讨论了使用混沌系统、压缩和 S 盒的图像加密技术的实现。在该加密方案中，压缩用于隐藏（纯文本）图像的原始大小，同时也降低了该方案的时间复杂度。除此之外，在改进的范围混沌图的帮助下，为加密过程选择了一个特定的 S-box。详细讨论了所提出的方案，以及其标准的安全性分析和实验结果。这种改进的混沌映射和 S 盒提供了大的密钥空间和高水平的安全性。
