A Blockchain-based Security Approach Architecture for the Internet of Things

With the rapid development of Internet of things technology, IoT security problems are increasingly prominent. Blockchain is a new application model of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies, which provides a new solution to solve the security problems of IoT. This paper envisages a blockchain-based security approach architecture for IoT, which aims to construct a space of mutual trust between devices for reliable data transmission.
