Feasibility of Identity Authentication for IoT Based on Blockchain

Abstract

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.
