A new Physically Unclonable Function (PUF) variant was developed on an FPGA, and its quality evaluated. It is conceptually similar to PUFs developed using standard SRAM cells, except it utilizes general FPGA reconfigurable fabric, which offers several advantages. Comparison between our approach and other PUF designs indicates that our design is competitive in terms of repeatability within a given instance, and uniqueness between instances. The design can also be tuned to achieve desired response characteristics which broadens the potential range of applications.
