The evaluation of Physically Unclonable Function (PUFs) quality is an open problem, as the PUF represents a circuit signature which depends on process variation but also environmental conditions. In the literature, some metrics have been introduced. The considered metrics are often the randomness (max entropy), the uniqueness (two PUFs should be different), and the steadiness (Reliability of the result). The objective of our research topic is to propose a new method which allows to evaluate a silicon PUF, based on delay elements, at design stage without the need to have the circuit.
