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.

Temporal Dynamics Makes Memristive Physical Unclonable Functions More Secure and Ultra‐Lightweight

Advanced Electronic Materials, Volume 11, Issue 20, December 3, 2025.
A temporal PUF (TPUF) is reported, using the randomness of temporal dynamics of memristors as an entropy source. By exploiting temporal complexity, significant reduction of hardware overhead is achieved in the TPUF, from otherwise at least hundreds‐of‐memristors‐scale crossbar arrays to only a pair of memristors.

Correction of Bit-Aliasing in Memristor-Based Physically Unclonable Functions With Timing Variability

IEEE Access, 2019
The dependence between the write time and process variation of a memristor was investigated as a candidate physically unclonable function (PUF). Such write-time-based approach requires exact timing control of the programming pulse to achieve well ...
