The Internet of Things (IoT) system is a complex environment where various entities and devices communicate. IoT is used in fields like transportation, healthcare, and monitoring, linking smart devices with sensors through the Internet to collect data from the physical world. To protect this sensitive data from hackers, an IoT platform or architecture that ensures end-to-end privacy and security is essential. Although there are many security and privacy solutions for IoT that offer basic security needs like confidentiality, integrity, and authentication, traditional solutions fall short for the large-scale IoT paradigm due to its heterogeneous nature and resource-constrained devices. Hence, this research focuses on decentralized architectures. Block chain (BC) technology is gaining attention for addressing security and authoritarian issues. In this approach, a block chain smart contract is updated with an attack detection contract.
