A Model Design Using Blockchain and Smart Contracts Against Cyberattacks in Smart Home Systems

Abstract

The use of Internet of Things (IoT)-based smart home systems is rapidly becoming widespread today. The structure of smart devices and the inadequacy of security systems make these systems vulnerable to cyberattacks. Therefore, using a solid security mechanism is important for protecting personal data in smart home systems The main purpose of this study is to present a model that works on the blockchain and smart contract infrastructure to ensure the security of smart home systems against cyberattacks. This study is a design-based research that examines how blockchain and smart contracts can be integrated to increase smart home security. The blockchain technology used in the proposed model protects the integrity of data by providing a decentralized distributed ledger to eliminate possible attack vectors. Additionally, predefined security protocols are automatically executed thanks to the use of smart contracts, thus increasing the overall durability of the system. In thisway, the proposed model effectively reduces security vulnerabilities in smart home systems, ensures the immutability of data, prevents unauthorized changes, and offers an effective security solution against possible cyberattacks. As a result, the proposed model can be said to be a robust, efficient security solution for IoT networks and smart home systems.
