A Survey on the Applications of Blockchains in Security of IoT Systems
It provides a comprehensive overview for researchers and practitioners on applying blockchain to improve IoT security, but it is incremental as it synthesizes existing knowledge without new empirical results.
This survey paper reviews how blockchain technology can address security and integration problems in IoT systems, discussing its role in enhancing data integrity and device connectivity.
The Internet of Things (IoT) has already changed our daily lives by integrating smart devices together towards delivering high quality services to its clients. These devices when integrated together form a network through which massive amount of data can be produced, transferred, and shared. A critical concern is the security and integrity of such a complex platform to ensure the sustainability and reliability of these IoT-based systems. Blockchain is an emerging technology that has demonstrated its unique features and capabilities for different problems and application domains including IoT-based systems. This survey paper reviews the adaptation of Blockchain in the context of IoT to represent how this technology is capable of addressing the integration and security problems of devices connected to IoT systems. The innovation of this survey is that we present a survey based upon the integration approaches and security issues of IoT data and discuss the role of Blockchain in connection with these issues.
