Sustainable Paradigm for Computing the Security of Wireless Internet of Things: Blockchain Technology

Advanced computerization, emerging paradigm, and expeditious growth of the wireless Internet of Things (IoT) system functions with the use of sensors, actuators, and translators. The IoT network is an illustration of innovative automation and rapid growth wireless systems which exploit sensing, actuating, Artificial Intelligence, Blockchain Technology, and networking technologies for achieving the aims of the systems. Resources or constraints of the IoT objects explain the working of smart IoT systems. The expeditious growth and regular assessment of the IoT environment, increased security issues, and problems of the system are due to its wireless connectivity and cloud‐based centralized architectures, etc. Security and threats can become a crucial problem in any wireless networking system like the IoT, which hamper the computing power of the system and also reduce its efficiency. Various security threats to the IoT system include Signal or Radio Jamming, Spoofing, Malicious attacks, Denial of Service (DoS) attacks, Distributed Denial of Service (DDoS) attacks, Black Hole attacks, Sybil attacks, Data tampering, Tag cloning, etc. To address these threats, risks, and challenges, researchers have implemented many solutions with latest technologies such as Blockchain technology, IOTA, etc. In the current potential situation, Blockchain technology is the most recent, sustainable, and growing technology to deal with the security and threats to IoT applications, because of its peer‐to‐peer, immutable, and decentralized nature. The distributed behavior of Blockchain makes it compatible to integrate Blockchain with the IoT system. There is the need for further study to recognize more secure IoT systems which can overcome the numerous threats to security. In this chapter, our goal is to perform a systematic review of summarized existing problems and solutions related to security in the Blockchain‐based Internet of Things (BIoT) and the Internet of Things (IoT) systems. In this chapter, research questions (RQ) are used to illustrate the problems. Through the contribution of research questions and literature surveys we conclude with the potential security problems of the IoT as well as solutions using Blockchain.
