SECURITY IMPROVEMENTS OF INTERNET OF THINGS SYSTEMS

Abstract

In this paper, we discuss the security of the Internet of Things (IoT) which needs to utilize particular algorithms in order to offer low power consumption and a long lifespan, along with other parameters such as strong immunity against attacks, lower execution time and acceptable performance. The present work considers a simple lightweight security encryption algorithm (LSEA) to be compatible with IoT systems, named (LSEA-IoT) for improving the security issue in IoT devices. The new LSEA-IoT scheme has be implemented for encrypting texts and images data and several tests such as visual checking, histogram diagrams, entropy and correlation analyses are carried out in order to ensure the suitability of the LSEA algorithm. Simulation results show that the performance of LSEA based IoT scheme achieves acceptable security level in terms of histogram, entropy and correlation performances as well as it has a good execution time performance for different types of messages. Based on this analysis, it can be concluded that the proposed LSEA-IOT is a promising algorithm and can be considered as an appropriate nominee to be utilized for IoT devices and it can be used for real-time applications.
