New Hybrid Lightweight Data Encryption Algorithm for Operation System Protocol in Internet of Thing Environment

Abstract

Lightweight cryptography is an intriguing information security issue. Due to rising component utilization, time, power, and memory needs, lightweight cryptography is needed. In June 2013, the NSA created Speck, a suggested algorithm. This article presents an IoT device security solution for a building's rooms. This post also offers a secure way to protect hardware against robbers and building mishaps in schools, hospitals, companies, and homes. This work provides robust and fast encryption algorithms for military security. This proposal employs a lightweight technique to encrypt environmental data, whether urgent, fast, or normal. This article applies the SPECK method to sensor data from a collection of rooms in the company building using a simple encryption scheme. In this post, the Ethernet-shielding Arduino UNO3 is linked to another set of sensors to collect environmental data. One of Arduino's simple encryption methods, the PRESENT technique, encrypts sensor data from numerous corporate building rooms. PRESENT encrypts sensor data to protect it from hackers. The Raspberry Pi re-encrypts data using SPECK encryption before sending it to the PC over MQTT to publish subscriber data for further security. Secure, private, and ciphered output will be transferred to the cloud. Sensors, a Raspberry Pi, Ethernet shield Arduino devices, and a computer are needed. Python, Arduino IDE, and Raspberry OS are software needs.
