Security and IoT cloud federation: Design of authentication schemes

The advent of both Cloud computing and Internet of Things (IoT) is changing the way of conceiving information and communication systems. Generally, we talk about IoT Cloud to indicate a new type of distributed system consisting of a set of smart devices interconnected with a remote Cloud infrastructure, platform, or software through the Internet and able to provide IoT as a Service (IoTaaS). In this paper, we address such a challenging paradigm focusing on security in IoT Cloud Federation. In particular, we discuss several authentication schemes fitting different types of scenarios.
