Comprehensive Survey and Research Directions on Blockchain IoT Access Control

Abstract

The Internet of Things (IoT) is a widely used technology in the last decade in different applications. The Internet of things is wirelessly or wired to communicate, store, compute and track various real-time scenarios. This survey mainly discussed the core problems of Internet of things security and access control to unauthorized users and security requirements for IoT. The Internet of things is a heterogeneous device and has low memory, less processing power because of the small sizes. Nowadays, IoT systems are not sure and powerless to protect themselves against cyber attacks. It is mainly due to inadequate space in IoT gadgets, immature standards, and the lack of protected hardware and software design, development, and deployment. To meet IoT requirements, the authors discussed the limitations of traditional access control. Then the authors examined the potential to spread access control by implementing the safe architecture accommodated by the Blockchain. The authors also addressed how to use the Blockchain to work with and resolve some of the standards relevant to IoT security issues. In the end, an analysis of this survey shows future, open-ended problems, and challenges. It offers how the Blockchain potentially ensures reliable, scalable, and more efficient security solutions for IoT and further research work.

A Survey on Blockchain Envisioned Attribute Based Access Control for Internet of Things: Overview, Comparative Analysis, and Open Research Challenges

“…Besides, the authors also compare traditional AC schemes to blockchain-empowered approaches, identifying unresolved issues and potential areas for future research. Later, Hussain et al [38] discuss the challenges faced by IoT security, including AC for unauthorized participants and IoT security standards. The authors add the shortcomings of traditional AC techniques in meeting the security requirements of the IoT and evaluate the potential of employing blockchain technology to provide a secure framework for AC.…”

A Systematic Literature Review and Meta-Analysis on Scalable Blockchain-Based Electronic Voting Systems

“…Bitcoin was the first use of Blockchain technology. It is a digital currency based on Blockchain technology and can be used to deal online in the same manner as using money to trade in the natural world [ 79 ]. Because of the success of Bitcoin, Blockchain technology may be used in various industries and services, including financial markets, IoT, supply chains, voting, medical treatment, and storage.…”

Blockchain-Based Access Control Techniques for IoT Applications

“…Authors did not make the difference between the criteria concerning blockchain technology and those relating to access control. [20] 2021…”

“…In [20], Hussain et al presented a survey on recent blockchain-based access control schemes. They used two groups to classify these solutions.…”

“…Moreover, it is shown that in [16,18,19] authors took into account only one criterion: Cr5, Cr3, and Cr1, respectively. Furthermore, Hussein et al [20] managed Cr3 and Cr9 criteria. Furthermore, it can be noticed that none of the previously cited comparison criteria was managed by Shantanu et al [21].…”
