Abstract
In this paper we study the reliability of ring oscillator PUFs. We correlate the reliability with the distance between the measured oscillation frequencies, for different operating conditions. We propose a reliability evaluation metric based on differential frequency threshold, which allows the design of a robust PUF. In addition, we evaluate the characteristics of the resulting PUF and we devise a scenario for guaranteeing the overall reliability by selecting appropriate error correcting codes.
