A Survey of How to Use Blockchain to Secure Internet of Things and the Stalker Attack

Abstract

The Internet of Things (IoT) is increasingly a reality today. Nevertheless, some key challenges still need to be given particular attention so that IoT solutions further support the growing demand for connected devices and the services offered. Due to the potential relevance and sensitivity of services, IoT solutions should address the security and privacy concerns surrounding these devices and the data they collect, generate, and process. Recently, the Blockchain technology has gained much attention in IoT solutions. Its primary usage scenarios are in the financial domain, where Blockchain creates a promising applications world and can be leveraged to solve security and privacy issues. However, this emerging technology has a great potential in the most diverse technological areas and can significantly help achieve the Internet of Things view in different aspects, increasing the capacity of decentralization, facilitating interactions, enabling new transaction models, and allowing autonomous coordination of the devices. The paper goal is to provide the concepts about the structure and operation of Blockchain and, mainly, analyze how the use of this technology can be used to provide security and privacy in IoT. Finally, we present the stalker, which is a selfish miner variant that has the objective of preventing a node to publish its blocks on the main chain.

How Blockchain Technology Can Benefit Marketing: Six Pending Research Areas

“…While the need for heightened online privacy protection is rising, blockchain technology can alleviate many issues impeding consumers from shopping online. For example, consumers can entrust their PII on a blockchain platform since transactions are not bound to real identities once they are routed to a random set of points in the network (Jesus et al, 2018). Online privacy of consumers can be adequately engineered to control the access of network members to the information contained in the blocks.…”

A quick synopsis of blockchain technology

“…It does more that merely involve in economic and financial applications. The applications includes e-health (Rifi et al, 2017), education (Grech and Camilleri, 2017), arts, culture, governance, supply chain, science, distributed cloud storage (Li et al, 2018), digital rights management (Ma et al, 2018), and internet of things (Jesus et al, 2018). The most promising application is of Blockchain 3.0 is the smart cities (Sun et al, 2016;Sharma and Park, 2018) which covers most of the elements including mobility, living governance, etc.…”

Blockchain of Things (BCoT): The Fusion of Blockchain and IoT Technologies

“…The works of Sun et al (Sun, Yan, & Zhang, 2016), Samaniego & Deters (Samaniego & Deters, 2016) and Reyna et al (Reyna, Martín, Chen, Soler, & Díaz, 2018;Atzori, Iera, & Morabito, 2010) are worth mentioning in this regard. Many studies (Jesus, Chicarino, Albuquerque, & Rocha, 2018;Kouicem, Bouabdallah, & Lakhlef, 2018) The Filament 1 research projects involve designing and developing a wireless network cable of controlling "any" systemranging from street bulbs of a city to burglar alarm system of any office. That being said, the projects highly focus on the use of blockchain and smart contract to enable smart devices (such as sensors, smart refrigerator, smart TV or any other smart appliances) to interact with each other via seamless Machine-to-Machine (M2M) communications including discovering and exchanging messagesautonomously, without being controlled by any central authority.…”
