Abstract

The rapid development of Smart Home IoT (SH-IoT) technologies presents considerable challenges in information security and privacy protection, including recurrent data breaches and privacy violations. Addressing these issues, this study introduces a multi-image encryption algorithm utilizing a novel 3D discrete hyperchaotic map to strengthen SH-IoT security. The solution simultaneously encrypts multiple images by integrating compressive sensing, while novel encryption units disrupt pixel correlations through cross-plane permutation and ring chain diffusion. Demonstrating remarkable adaptability, the algorithm dynamically adjusts compression ratios according to device capabilities and application demands, optimizing the security-efficiency-quality balance. Experimental validation confirms exceptional performance: achieving 99.6095% NPCR and 33.4597% UACI, along with a 2481 kb/s encryption speed at 0.5 compression ratio—substantially outperforming non-compressed scenarios.

集成超混沌和压缩感知的智能家居物联网多图像加密新方案

智能家居物联网（SH-IoT）技术的快速发展给信息安全和隐私保护带来了相当大的挑战，包括反复发生的数据泄露和隐私侵犯。为了解决这些问题，本研究引入了一种利用新型3D离散超混沌映射的多图像加密算法来增强SH-IoT安全性。该解决方案通过集成压缩感知同时加密多幅图像，而新的加密单元通过跨平面排列和环链扩散破坏像素相关性。该算法具有较强的适应性，可根据设备性能和应用需求动态调整压缩比，优化安全-效率-质量的平衡。实验验证证实了卓越的性能：在0.5压缩比下实现99.6095%的NPCR和33.4597%的UACI，以及2481 kb/s的加密速度-大大优于非压缩场景。

期刊介绍： The quality of software, well-defined interfaces (hardware and software), the process of digitalisation, and accepted standards in these fields are essential for building and exploiting complex computing, communication, multimedia and measuring systems. Standards can simplify the design and construction of individual hardware and software components and help to ensure satisfactory interworking. Computer Standards & Interfaces is an international journal dealing specifically with these topics. The journal • Provides information about activities and progress on the definition of computer standards, software quality, interfaces and methods, at national, European and international levels • Publishes critical comments on standards and standards activities • Disseminates user''s experiences and case studies in the application and exploitation of established or emerging standards, interfaces and methods • Offers a forum for discussion on actual projects, standards, interfaces and methods by recognised experts • Stimulates relevant research by providing a specialised refereed medium.
