Chaos influence different fields of science and technology. The development of sciences is at peak expected to the rapid broadcast of information with the smart machine in constrained resources atmosphere. With the help of our smartphone, we can easily access the information within no time and with much ease. This ease makes our information open and can be accessed from the web or misuse by any person. To secure our information on the internet of things (IOTs), lightweight cryptographic algorithms were introduced. We offered an efficient lightweight confusion component scheme constructed on the composition of chaotic iterative maps. The proposed chaotic lightweight substitution box (S-box) offers decent cryptographic characteristics. The suggested chaotic S-box is used for adding a confusion layer in small lightweight block cipher algorithms. The outcome of cryptographic characteristics displays that the anticipated chaotic Substitution box is appropriate for the lightweight block cipher in a constrained source environment.

混沌影响着科学和技术的不同领域。在有限的资源环境下，智能机将迅速传播信息，因此科学的发展有望达到顶峰。借助我们的智能手机，我们可以随时随地轻松地轻松访问信息。这种轻松使我们的信息开放，可以从网上访问或任何人滥用。为了保护我们在物联网（IOT）上的信息，引入了轻量级的加密算法。我们提供了一种有效的轻量级混淆组件方案，该方案基于混沌迭代图的组成而构建。提出的混沌轻量级替换盒（S-box）提供了不错的加密特性。建议的混沌S-box用于在小型轻量级分组密码算法中添加混淆层。
