Blockchain as a Solution for Internet of Things Security: a Survey
Keywords:
IoT, Blockchain, The Integration between IoT and blockchain.Abstract
The Internet of Things (IoT) has revolutionized device interactions, enabling automation and connectivity, but security and trust issues have hindered its widespread adoption. Blockchain technology is seen as the optimal way to address these difficulties due to its immutable and decentralized characteristics. This article examines the capacity of blockchain technology to mitigate significant security and trust issues in the expanding IoT environment. This study conducts a thorough literature analysis to analyses how the decentralised, irreversible, and transparent characteristics of blockchain enhance security and trust in IoT networks. This study analyse and classify prevalent security concerns pertaining to the IoT layered architecture. Additionally, catalogue and illustrate the most common challenges in both blockchain networks and IoT network during the integration, and the advantages of this combination between those two technologies. Furthermore, the limitation of blockchain with some IoT application.
