An ultra-low energy PUF matching security platform using programmable delay lines

Abstract

We have proposed a new security platform: physical unclonable function (PUF) matching using programmable delay lines (PDL). Our platform inherits good security properties of standard PUFs, such as low energy, low delay, and unclonability. However, standard PUF-based security protocols induce high computational resources of at least one involved party. To resolve this issue, we take advantage of PDL technology to match standard PUFs in such a way that two PUFs have the same challenge response mapping function. The matched pair of PUFs enables a majority of protocols to be executed in an ultra low energy, low latency manner for all the involved parties.
