Towards the Integration of Blockchain and IoT for Security Challenges in IoT

Abstract

Internet of things (IoT) technology plays a vital role in the current technologies because IoT develops a network by integrating different kinds of objects and sensors to create the communication among objects directly without human interaction. With the presence of internet of things technology in our daily comes smart thinking and various advantages. At the same time, secure systems have been a most important concern for the protection of information systems and networks. However, adopting traditional security management systems in the internet of things leads several issues due to the limited privacy and policies like privacy standards, protocol stacks, and authentication rules. Usually, IoT devices has limited network capacities, storage, and computing processors. So they are having more chances to attacks. Data security, privacy, and reliability are three main challenges in the IoT security domain. To address the solutions for the above issues, IoT technology has to provide advanced privacy and policies in this large incoming data source. Blockchain is one of the trending technologies in the privacy management to provide the security. So this chapter is focused on the blockchain technologies which can be able to solve several IoT security issues. This review mainly focused on the state-of-the-art IoT security issues and vulnerabilities by existing review works in the IoT security domains. The taxonomy is presented about security issues in the view of communication, architecture, and applications. Also presented are the challenges of IoT security management systems. The main aim of this chapter is to describe the importance of blockchain technology in IoT security systems. Finally, it highlights the future directions of blockchain technology roles in IoT systems, which can be helpful for further improvements.

Security challenges of blockchain in Internet of things: Systematic literature review

“…IoT technology must supply developed policies and privacy in this huge inclusion source of data to solve the mentioned problems. BC is a trending technology in the management of privacy to supply security 107 . Currently, IoT devices are impotent and insecure about defending themselves.…”

Critical Concerns of Deploying Blockchain in Internet of Things Applications

“…Study Recommendations/research directions Security [39] • Establishment of a robust trust environment. [40] • The needs for cryptographic development, stability, and security should be addressed.…”

“…Another exciting study topic is allowing IoT devices and gateways to use blockchain without requiring a centralized block validation pool [52]. Due to these applications' high networking costs and performance needs, blockchain scalability remains a major concern for its adoption in digital finance [39]. The large volume of transaction data worsens lowthroughput concerns in the IoT.…”

Systematic literature review on the security challenges of blockchain in IoT-based smart cities

“…Health-care associations are confronting a major issue in sharing clinical data among various partners without giving up the protection and honesty of data. To store and offer such a huge volume of health-care data safely is a significant study matter (Kumar et al , 2020). Health-care experts are presently adopting IoT-depended wearable technology to streamline the treatment and diagnosis procedures (Dwivedi et al , 2019).…”
