In this paper, an analysis regarding the influence of the chosen locations of the ring oscillators in the performance of a ring oscillator Physically Unclonable Function has been carried out. For this purpose, five different strategies to select a small set of locations out of a big set of locations to construct a PUF have been proposed and compared. The analysis reflects that, depending on the chosen selection strategy, the quality of the PUF can be greatly affected, especially in terms of uniqueness.
