A Robust Lightweight Algorithm for Securing Data in Internet of Things Networks

Abstract

One of the modern technologies that link millions of different devices together, is the technology called Internet of things. The amount of data exchanged between these devices is very large. Therefore, it requires high protection for that data. Also, those devices are small size and limited resources. Therefore, conventional cryptography will take long process on the internet of things due to complex mathematical operations and an increase in the number of rounds, which leads to energy resource consumption for devices. In this paper, a lightweight cryptographic algorithm is suggested. The algorithm uses simple mathematical operations (XOR, XNOR, shifting, swapping). The algorithm works on a combination of Feistel and SP architectural methods to increase the complexity of the encryption. The algorithm has been compared to other algorithms in terms of structure, security, and flexibility.
