Towards a Standardized Identity Federation for Internet of Things in 5G Networks

With the upcoming introduction of 5G networks for our daily usage and convenience and with the purpose of accommodating a countless amount of Internet of Things (IoT) devices and applications alongside the billion devices that already use the network (e.g. mobile phones), one of the key aspects for its success is to ensure to these upcoming devices enhanced but affordable security. With this paper, we present a solution that introduces an Identity Federation mechanism that reuses the SIM authentication for cellular IoT devices, enabling single sign-on features. This solution aims to relieve the responsibility of IoT providers for developing (proprietary) device identity management mechanisms while allowing to reduce operation costs overall.
