Secure and Efficient IOT Communication using Lightweight Cryptography in MQTT Networks

Abstract

The Internet of Things (IOT) is rapidly expanding and quietly revolutionizing various industries by enabling seamless communication between devices. From smartphones to smart home systems, IOT has become an essential part of our everyday lives, offering a wide array of applications. However, while IOT devices are highly efficient in their functionality, they often lack robust security measures. This is a significant concern, as these devices typically operate with limited computing power, memory, and energy resources. These constraints create a resource-constrained environment, making IOT systems particularly vulnerable to security threats. To address these challenges, this project implements a method that integrates lightweight cryptographic algorithms, such as AES, PRESENT, SPECK, and RECTANGLE with the MQTT protocol. This combination ensures strong data encryption and decryption while facilitating secure and efficient data transmission.
