Physical Unclonable Functions (PUF) are novel chip identifiers with an extensive array of uses in security applications. In this paper, we propose a novel PUF that has exponentially large Challenge/Response ($C/R$) space in a given area, while being resistant to modeling attacks at the same time. We name this design S-ArbRO PUF. We study the variability of the proposed PUF and its reliability to temperature variations. In addition, we perform a modeling attack on the PUF to get an insight into its resistance to modeling.
