Abstract

This paper introduces two prominent lightweight ciphers: XTEA and RECTANGLE. The exposition provides a detailed elucidation of their respective design principles, security features, and suitability for IoT applications. It is essential to comprehend how these ciphers operate, and this section affords readers a comprehensive insight into their inner workings.

The study takes a pivotal turn as we assess the hardware implementation metrics of both ciphers on an FPGA platform. This assessment reveals the resource efficiency of each cipher, with RECTANGLE emerging as the more resource-friendly choice. Such evaluations are vital in enabling informed decisions when selecting cryptographic solutions for resource-constrained environments.

An indispensable facet of this study revolves around the evaluation of randomness, a paramount factor in cryptographic security. To accomplish this, we employ the NIST Test Suite to scrutinize the randomness exhibited by both XTEA and RECTANGLE. The outcomes of these tests provide valuable insights into the cryptographic strength of each cipher. Notably, XTEA demonstrates superior randomness in certain tests, including the Linear Complexity Test, showcasing its unique attributes.

In conclusion, this paper underscores the pivotal role of lightweight cryptography in fortifying the security of IoT and IoE ecosystems. Through a meticulous comparative analysis of two prominent lightweight ciphers, it offers invaluable insights for researchers and practitioners navigating the complex landscape of interconnected devices and services. The findings of this study contribute significantly to the ongoing discourse surrounding the delicate equilibrium between security imperatives and the resource constraints inherent to IoT environments.
