Three counter value based ROPUFs on FPGA and their properties
Original language description
This paper investigates the behavior of the Physical Unclonable Function (PUF) design proposed in our previous work that is based ring oscillators (ROs). Our approach is able to extract multiple output bits from each RO pair in contrary to the classical approach, where frequencies of ROs are compared. We study the behavior of our PUF design together with other two similar proposals that are also based on extracting PUF bits from counter values. In this work we compare the behavior of three PUF designs that are based on extracting PUF bits from counter values with one of them being proposed in our previous work. We evaluate these proposals at both stable and varying temperature and voltage in order to determine their robustness. The results show that our proposed technique, the frequency ratio, is the most reliable one. Furthermore, we compare the behavior of all of the three designs when mutually asymmetric and symmetric ROs are used. All of the measurements were performed on Cmod S7 FPGA boards (Xilinx XC7S25-1CSGA225C).
