IoT Security Based on Smart Contracts: Classification of Algorithms, Complexity, Robustness and Fields of Application

In recent years, as data processing and storage technologies have advanced, the need to ensure computer system security and information confidentiality on all types of networks has grown significantly. The emergence of the Internet of Things (IoT) has led to interconnected objects using various communication protocols through a new generation of Internet networks. The increasing number of connected objects worldwide demands improved methods and techniques to secure these networks, particularly considering the potential presence of sensitive data. Consequently, network security has become a primary focus for numerous computer science researchers, with a particular emphasis on enhancing security techniques and data confidentiality for all participants or devices involved in a network architecture. In response to these challenges, several solutions based on Blockchain technology have been developed to secure Internet of Things networks. These solutions employ smart contracts to ensure verified transaction execution while adhering to authentication, confidentiality, and data integrity rules. This article aims to explore the security solutions for the Internet of Things based on smart contracts, evaluating factors such as complexity, robustness, and fields of application.
