Probing attacks to arbiter PUFs (physical unclonable functions) using a time-resolved emission microscope are evaluated by simulation. It is assumed that signal delay in the arbiter PUF chip is measured directly by using a time-resolved emission microscope. Only two challenge inputs are required to do that. A simple procedure can predict the response of the arbiter PUF. The relationship between the rate of successful response estimation and the accuracy of signal timing measurement is evaluated by simulation. The simulated results show the rate of successful response estimation is 70% when the accuracy is around 30 ps. A time resolution of 12.5 ps has been achieved by the commercial time-resolved emission microscope, so that this result shows the feasibility of the probing attacks to arbiter PUFs using a time-resolved emission microscope.
