Abstract	As the number and variety of connected objects continue to grow and the devices themselves become smarter, IoT has demonstrated to be the foremost rising innovation where millions of gadgets can interface to the web which makes the life attainable with no human intercession. However, the security and privacy of this IoT environment face some issues that must be overcome to meet the novel solution for IoT applications with no margin for error. Hence, secure architecture for centralized servers is necessitating maintaining the authenticity and protection of information. However, centralized architecture suffers from some challenges viz. reduction in performance, single point of failure and prone to attacks which could be addressed through decentralized or distributed architecture. Blockchain, being decentralized in nature, immutable in function, transparent in-process and reliable without a trusted third party, could be efficient attention for addressing IoT security challenges. In this research work the security concerns like access control mechanisms for IoT applications like smart city, smart healthcare system through Blockchain innovation is addressed. Blockchain being a distributed ledger provides an approach to securely store the data cryptographically. Specifically, proposed work intend to cover different access control methods for the protection of information and IoT security. This paper makes an exhaustive review of how decentralized architecture using Blockchain might potentially improve IoT access control. © 2020 IEEE.
