Abstract

Abstract : Physical Unclonable Functions In article number 2210621, Bowen Zhu, Hong Wang, and co‐workers use printed epsilon‐type‐structure transistor arrays with a modified indium tin oxide coffee‐ring structure to construct physical unclonable functions (PUFs) that demonstrate near‐ideal uniformity, uniqueness, randomness, reliability, and low power consumption. Additionally, the PUFs are secure against attack by a powerful machine‐learning model without post‐processing. The epsilon‐type structure provides a printable, simple strategy for high‐quality and large‐scale hardware secure primitives.
