Research on the Applications of Physically Unclonable Functions within the Internet of Things

This paper presents a overview over research activities in the field of Physically Unclonable Functions (PUFs) that reach into the domain of the Internet of Things (IoT) and summary of their outcomes. After brief introduction PUF technology and its basic properties, paper analyses one of most common PUF types, SRAM PUF, on selected set of commodity hardware. The paper also presents the authentication scheme, based on SRAM PUF, for resource-constrained embedded devices especially designed to be employed in the domain of the Internet of Things (IoT).This work was partially supported by by the Austrian Ministry for Transport, Innovation and Technology under the framework of "IKT der Zukunft" with the FFG grant agreement project 848732
