Popis:	In this paper, a new Physically Unclonable Function (PUF) has been implemented and tested. The idea behind this PUF is to compare the bias of the same Galois ring oscillator implemented in different locations within the FPGA. The implemented PUF has been compared to a Ring Oscillator PUF in terms of reproducibility, random-like response and uniqueness. Furthermore, the spatial correlation of the bias of the Galois oscillators has been studied and compared to the spatial correlation of the frequency of regular ring oscillators.
