Physical unclonable functions (PUFs) represent a class of security primitives that exploit the intrinsic randomness in material properties to generate unique digital fingerprints. By harnessing the ...

2T complementary architecture of one-time-programmable memory (OTP) in a foundry logic CMOS chip. It was then used to realize the PUF (Physical unclonable function), and the combination with the AI ...

a, An illustration of liquid crystal polymer-based random wrinkles observed using a microscope and converted into a binary code, random and unique, and used as a PUF. Liquid crystals have different ...

Atomic-scale imperfections in graphene transistors generate unique wireless fingerprints that cannot be copied or predicted, offering a new approach to hardware security for IoT devices. (Nanowerk ...

In cryptography and within embedded security ICs, the physically unclonable function (PUF) is used to create keys that are generated on-demand and instantaneously erased once used. Because PUF depends ...
