Blockchain and Distributed Ledger Technologies for IoT Security: A Survey paper

As the Internet of Things (IoT) continues to grow, the security concerns associated with this technology become increasingly important. Blockchain and Distributed Ledger Technologies (DLTs) are emerging as potential solutions for IoT security due to their decentralized and immutable nature. In this survey paper, we provide a comprehensive overview of the state-of-the-art research in the use of blockchain and DLTs for IoT security. We begin by introducing the basic concepts of blockchain and DLTs, followed by a discussion of their potential applications in IoT security. We then review the existing literature on the topic, including both academic and industrial research. We categorize the literature into different application areas, such as authentication, access control, and data integrity. Finally, we discuss the open research challenges and potential future directions for the use of blockchain and DLTs in IoT security. This survey paper provides a valuable resource for researchers and practitioners interested in understanding the current state-of-the-art research in this important area of IoT security.
