Ring oscillator physical unclonable function with multi level supply voltages
Shohreh Sharif Mansouri, Elena Dubrova · 2012
In this paper we introduce a new type of Ring Oscillator PUF (RO-PUF) in which the inverters composing the ring oscillators can be supplied by independent voltages. This new RO-PUF can improve the reliability of the PUF in case of temperature variations.
