An Energy-Efficient PUF Design
Hongxiang Gu, Teng Xu, Miodrag Potkonjak · 2016
Physical unclonable functions (PUFs) take advantage of the effect of process variation on hardware to obtain their unclonability. Traditional PUF design only focuses on the analog signals of circuits. An arbiter PUF, for example, generates responses by racing delay signals. Implementations of such PUFs usually employ large area and power consumption while providing very low throughput.
