An Identity Management Framework for Internet of Things

The Internet of Things (IoT) has been developing rapidly in the past few years. In IoT, an enormous number of smart devices are connected to the network, where communication and interaction occurs extensively among end users, smart devices and Internet services. Due to the great diversity of devices, broader scope of interactions and other characteristics of IoT, current IdM model for Internet needs to be extended and improved. The objective of this article is to analyze the main features of IoT and key issues of the IdM for IoT, and then present an IdM framework for IoT, which consists of three parts: the standard information model, user-centric architecture and multi-channel authentication.
