SYSTEMATIC LITERATURE REVIEW FOR LIGHTWEIGHT AUTHENTICATION ALGORITHM IN THE IoT

The Internet of Things (IoT) being a promising technology of the future is expected to generate a tremendous amount of data that may be exposed to security flaws. Hence, to protect IoT applications from hackers, lightweight cryptography has been identified as one of the suitable mechanisms since it is designed to fulfil security demands in resource-constrained hardware and software. This paper aims to analyse the current security requirements in designing lightweight cryptography for IoT applications, specifically for integrity and authentication algorithms. There are three objectives to focus on: Determine the current state of integrity and authentication research, investigate the integrity and authentication requirements, and analyse the lightweight authentication algorithm currently used. The Kitchenham systematic review method was adopted using a four-step process. The selected articles in this study were retrieved from four reputable databases and 57 of them were deemed suitable for analysis after meeting the selection criteria. From this systematic literature review, it was discovered that there were three active research focuses on the IoT. The research focuses were mostly on cyberattacks against IoT applications, system security requirements and algorithms for lightweight authentication. Furthermore, the analysis also revealed the convergence of lightweight authentication algorithms to ensure the future sustainability of applications. This study may provide researchers with a reference in designing lightweight authentication algorithms to achieve the desired security requirements for sustainable security management in IoT.
