IoT is one of the most important and profitable projects proposed by Kevin Ashton since 1999. One of the most critical issues in maintaining communication between things and protecting the data is the security issue of IoT. So far, different strategies have been made to maintain safe security. In this paper, we provide a Five-Layers model by adding two security layers based on BlockChain. We show that blockchain smart contracts are a solution to enhance IoT security and prevent infiltration into the network.
