Abstract

Objective: To perform attack analysis on new developed hybrid-SIMON-SPECKey lightweight cryptographic algorithms and compare its strength with existing SIMON and SPECK Lightweight cryptographic algorithm. Methods: A hybrid-SIMON-SPECKey algorithm is the combination of round function of SIMON and key scheduling of SPECK algorithm. Both SIOMN & SPECK algorithm are used for securing resource constrained devices. In this research work, avalanche effect method is used to analyze attack resistance property of algorithm. Findings: Newly developed Hybrid algorithm shows better results in terms of execution time and memory consumption. As compared to SIMON, hybrid version of algorithm consumes 50% less time and 20% less memory, which makes it efficient. Strict Avalanche criteria for SIMON is 89%, that of SPECK is 90% and in case of hybrid algorithm, it is 90% at start position but when the character is flipped or changed at the end position of plain text then SAC is more (87%) in case of hybrid algorithm as compared as SIMON and SPECK algorithms. Hence, newly developed algorithm showed improved results with equally resistance to the attack as compared to SIMON & SPECK. Novelty and applications: The novelty lies in the creation of a hybrid lightweight cryptographic algorithm that combines the feistel structure of SIMON with the key scheduling function of SPECK. This hybrid approach aims to leverage the strengths of both algorithms, potentially providing a more robust and efficient solution for resource-constrained IoT devices. In section 3.1 comparative analysis is done which show that hybrid algorithm outperforms in term of time and memory consumption as well a strength of newly developed hybrid algorithm is evaluated using avalanche effect which shows that it is at par with base algorithms.

物联网应用中混合 SIMON-SPECKey 轻量级加密算法的攻击分析

目的对新开发的混合 SIMON-SPECKey 轻量级加密算法进行攻击分析，并将其与现有的 SIMON 和 SPECK 轻量级加密算法进行强度比较。方法：混合-SIMON-SPECKey 算法是 SIMON 循环函数和 SPECK 算法密钥调度的结合。SIOMN 和 SPECK 算法都用于保护资源有限的设备。在这项研究工作中，使用了雪崩效应方法来分析算法的抗攻击性。研究结果新开发的混合算法在执行时间和内存消耗方面显示出更好的效果。与 SIMON 算法相比，混合算法的时间消耗减少了 50%，内存消耗减少了 20%，因此效率更高。SIMON 算法的严格雪崩标准为 89%，SPECK 算法的严格雪崩标准为 90%，而混合算法在起始位置的严格雪崩标准为 90%，但当字符在纯文本结束位置翻转或改变时，混合算法的严格雪崩标准比 SIMON 和 SPECK 算法更高（87%）。因此，与 SIMON 和 SPECK 算法相比，新开发的算法显示出更好的结果，具有同样的抗攻击性。新颖性和应用：新颖之处在于创建了一种混合轻量级加密算法，该算法结合了 SIMON 的 feistel 结构和 SPECK 的密钥调度功能。这种混合方法旨在利用两种算法的优势，为资源受限的物联网设备提供更稳健、更高效的解决方案。在第 3.1 节中进行了比较分析，结果表明混合算法在时间和内存消耗方面优于基础算法，并使用雪崩效应评估了新开发的混合算法的强度，结果表明它与基础算法相当。关键词攻击分析、密码、解密、加密、轻量级密码学、物联网设备、资源受限设备
