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 ...

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 ...

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 ...

A technical paper titled “CNT-PUFs: Highly Robust and Heat-Tolerant Carbon-Nanotube-Based Physical Unclonable Functions for Stable Key Generation” was published by researchers at Chemnitz University ...

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 ...

Check out more TechXchange Talks videos. Crossbar's latest resistive RAM (ReRAM) technology can be used to implement physically unclonable functions (PUFs). ReRAM has garnered interest as an embedded ...

A conductive hydrogel transforms its random internal structure into a secure, unclonable signature, addressing the challenge of counterfeit detection and reliable authentication in flexible devices ...

A Palo Alto security and authentication startup known for its “unclonable” silicon chips, relaunched Wednesday as Verayo in an effort to move its focus from government defense contracts to commercial ...
