Lightweight Encryption Algorithms, Technologies, and Architectures in Internet of Things: A Survey

Abstract

Internet of things is a fast-growing field of industry as a lot of IoT applications are introduced in the market. Its popularity is also growing because of its ease of use and its applications serving in vast domains. The demand for IoT deployment over a large scale is increasing at a swift pace. A lot of issues and challenges have worked on, and a lot remains to be explored and solved. It has become a focus of research. A considerable number of researches have contributed a lot in the field of IoT. However, still it is lagging in the security domain, so is the reason for concern for many researchers. There are few other concerns in IoT which are related to the security goals, requirements, challenges, and issues. This paper provides an overview of IoT along with presenting various privacy and security issues in it. The paper also shows how the security in IoT differs from the security in conventional systems. Various lightweight encryption techniques for IoT, limitations of IoT, IoT technologies, and architectures are discussed and compared in the paper.
