Complex Cryptographic and User‐Centric Physically Unclonable Functions Enabled by Strain‐Sensitive Nanocrystals via Selective Ligand Exchange

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.

Physically unclonable function using CMOS breakdown position [PDF]

2017 IEEE International Reliability Physics Symposium (IRPS), 2017
© 2017 IEEE. A novel physically unclonable function (PUF) utilizing the intrinsic randomness of oxide breakdown (BD) positions in CMOS transistors is presented. The advantages of this approach are studied and validated by measurements on test-chips fabricated in a commercial 40nm CMOS process. Experiments show that the required soft BDs can be reliably

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.
