The purpose of this paper is to describe identity concepts in the Internet of Things. Identity mechanisms in the Internet of Things are different from those in the classic web.
Furthermore this paper proposes a terminology for Identity management in the Internet of Things. This should help to facilitate discussions and work in this area without the need to define basic terms again.

Introduction

...

 The “Internet of Things” (IoT) is beginning to evolve and early solutions are now being implemented. We can find implementations in areas like logistics, farming, industry, home automation and many others. But its restrictions become obvious as we try to connect solutions of different vendors, communities or standard groups. From a business point of view the IoT enables a plethora of new opportunities, use cases and scenarios. From a technical point of view the IoT consists of uncountable devices, sensors or actuators or simply objects connected to services in the Internet. Today, devices and sensors speak a lot of different protocols, but most of them are not HTTP. That is why application development in the IoT is hard to be implemented. There is a lack of decent application integration layers. The next logical step is to use common Web technologies for the IoT. Identity management is one of the most important common technologies.
