A formal definition and a new security mechanism of physical unclonable functions

, 2012
The characteristic novelty of what is generally meant by a "physical unclonable function" (PUF) is precisely defined, in order to supply a firm basis for security evaluations and the proposal of new security mechanisms.

Design Impedance Mismatch Physical Unclonable Functions for IoT Security

Active and Passive Electronic Components, 2017
We propose a new design, Physical Unclonable Function (PUF) scheme, for the Internet of Things (IoT), which has been suffering from multiple-level security threats. As more and more objects interconnect on IoT networks, the identity of each thing is very

Sensitivity of the Threshold Current for Switching of a Magnetic Tunnel Junction to Fabrication Defects and Its Application in Physical Unclonable Functions

Applied Sciences
A physical unclonable function (PUF) leverages the unclonable random variations in device behavior due to defects incurred during manufacturing to produce a unique “biometric” that can be used for authentication.
