The security of digital content during transmission and storage through insecure communication links and databases is a challenging issue in today's world. In this article, an encryption scheme based on fractal Tromino and Chebyshev polynomial-based generated chaotic matrix is presented. The scheme fulfills the most fundamental aspect of encryption that is diffusion and confusion. For confusion highly non-linear, pre-defined S-boxes are used. The proposed scheme has been tested using state-of-the-art key performance indicators including differential analysis, statistical analysis. Information entropy analysis, mean square error, and NIST-based randomness analysis. The encrypted images have the highest practically achievable entropy of 7.999 and the time analysis shows that the proposed system is suitable for real-time implementation. The rest of the results indicates that the proposed cryptosystem possesses high immunity toward various attacks. The security analysis compared with the existing scheme shows the strength of the suggested scheme.

基于分形 Tromino 和 Chebyshev 多项式的高效图像加密方案

在当今世界,通过不安全的通信链接和数据库传输和存储数字内容的安全性是一个具有挑战性的问题。本文提出了一种基于分形 Tromino 和 Chebyshev 多项式生成混沌矩阵的加密方案。该方案实现了加密的最基本方面,即扩散和混淆。对于高度非线性的混淆,使用预定义的 S-box。所提出的方案已经使用最先进的关键性能指标进行了测试,包括差异分析、统计分析。信息熵分析、均方误差和基于 NIST 的随机性分析。加密图像的最高实际可实现熵为 7.999,时间分析表明所提出的系统适合实时实现。其余的结果表明,所提出的密码系统对各种攻击具有很高的免疫力。与现有方案相比的安全性分析显示了建议方案的强度。
