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 ...

The Secure Embedded Systems (SES) lab in the Center for Embedded Systems for Critical Applications (CESCA) at Virginia Tech, has demonstrated a novel Physical Unclonable Function (PUF), implemented in ...

Physically unclonable functions (PUFs) are emerging as a novel way to protect a variety of ICs. In today’s world of cyber threats, vulnerabilities, insecure networks and hardware, and intrusions, it ...

Nearly 600 cell lines commonly used in biomedical research today are misidentified or cross-contaminated, according to a recent paper and several additional studies. One estimates that nearly 33,000 ...

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 ...

Despite the rigorous process controls for factories, anyone who has worked on hardware can tell you that parts may look identical but are not the same. Everything from silicon defects to microscopic ...

The development comes from Rice University, where scientists have applied integrated circuit design to construct new approach for creating secure keys and identifiers on Internet of Things ...

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 ...

Discovering that your new designer handbag or gold watch is a fake is costly and annoying, and counterfeit medical devices or drugs could have even more serious consequences. But seemingly as soon as ...
