Authentication of IC based on Electromagnetic Signature [PDF]
, 2016 IC Counterfeiting is becoming serious issue. The approach discussed here is to use Electromagnetic (EM) input to an IC and measure its EM input output response. The idea is to extract a signature from EM response which should be unique to one IC. The

Advanced Functional Materials, Volume 36, Issue 28, 7 April 2026.This study presents a dynamic interaction between liquid resins and photopolymerized structures enabled by an in situ light‐writing setup. By controlling a three‐phase interface through localized photopolymerization, which provides physical confinement for the remaining uncured resin regions, the approach establishes a programmable pathway that ...

Public Physical Unclonable Functions
Proceedings of the IEEE, 2014 A physical unclonable function (PUF) is an integrated circuit (IC) that serves as a hardware security primitive due to its complexity and the unpredictability between its outputs and the applied inputs. PUFs have received a great deal of research interest and significant commercial activity.

Advanced Electronic Materials, Volume 12, Issue 8, 20 April 2026.A concealable physical unclonable function (PUF) based on an array of 384 nanoscale voltage‐controlled magnetic tunnel junctions is demonstrated. The PUF operates without any external magnetic field. It uses a combination of deterministic and stochastic switching mechanisms, based on the spin transfer torque and voltage‐controlled magnetic anisotropy ...

Advanced Functional Materials, Volume 36, Issue 23, 19 March 2026.This study investigates electromechanical PUFs that improve on traditional electric PUFs. The electron transport materials are coated randomly through selective ligand exchange. It produces multiple keys and a key with motion dependent on percolation and strain, and approaches almost ideal inter‐ and intra‐hamming distances.
