Silicon Physical Unclonable Function resistant to a
1025-trial brute force attack in 90 nm CMOS

 

Abstract

A CMOS 90 nm physical unclonable function (PUF) based on analog signal processing and process variability has been realized, resistant to a brute force attack of more than 1025 trials. Experimental measurements show that the circuit exhibits 38 uW power consumption. Process and temperature monitor and compensator keep the experimental BER below 0.1% at 125C or with a 10% VDD variation, with excellent accelerated aging behavior.
