A Comprehensive Systematic Review of Access Control in IoT: Requirements, Technologies, and Evaluation Metrics

Abstract

The Internet of Things (IoT) is an emerging technology with a very high market growth rate. In IoT, machines, and users from different levels need to collaborate to exchange data and share resources. IoT opens the door for a vast improvement in all human life aspects. However, the increasing adoption of IoT in many sectors makes it difficult to control security risks. For this reason, there is a need for more effort in both research and industry to address the risks and find convenient solutions. This systematic literature review delves deep into understanding the unique challenges and requirements posed by IoT environments. Through a detailed examination of 96 selected studies, this paper primarily addresses three research questions. The study concludes by summarizing key requirements, technologies, and metrics founded on our comprehensive analysis, aiming to steer further research in the domain. As IoT continues its expansion into various facets of our daily lives, there's a paramount need to integrate with emerging technologies, ensure scalability, and prioritize real-world implementations for the next wave of innovations in access control systems.INDEX TERMS access control, Internet of Things, IoT, security, systematic review.

SDACS: Blockchain-Based Secure and Dynamic Access Control Scheme for Internet of Things

“…Technologies such as access control, encryption, and blockchain are fortunately capable of addressing the challenges faced by IoT data sharing. Access control stands out as a leading technology for securing IoT data, permitting users to access data within specified limits, legally [7][8][9]. It is widely recognized that conventional access control models provide only broad and coarse-grained access control, rendering them inadequate for the typical open environments of the IoT.…”
