With the rapid development of the Internet of Things (IoT), more and more devices are connected to the Internet. As IoT devices are resource-constrained in terms of processing, storage and network capacity, it becomes a challenging task to ensure the access of IoT devices. Identity authentication is a key technology to prevent illegal users from access resources and permissions. Based on the principle of blockchain technology, combining blockchain technology with IoT, this paper proposes a blockchain system framework for IoT identity authentication, which implements the authentication between devices and cloud servers, IoT base stations as well as devices, and then analyzes its feasibility.
