Physical unclonable function
A physical unclonable function (sometimes also called physically unclonable function, which refers to a weaker security metric than a physical unclonable function), or PUF, is a physical object that for a given input and conditions (challenge), provides a physically defined "digital fingerprint" … Visa mer Early references about systems that exploit the physical properties of disordered systems for authentication purposes date back to Bauder in 1983 and Simmons in 1984. Naccache and Frémanteau provided … Visa mer In many applications, it is important that the output is stable. If the PUF is used for a key in cryptographic algorithms, it is necessary that error correction be done to correct any errors … Visa mer • PUF technology can be licensed from several companies including eMemory, or its subsidiary, PUFsecurity, Enthentica, ICTK, Intrinsic ID, Invia, QuantumTrace, Granite Mountain … Visa mer PUFs depend on the uniqueness of their physical microstructure. This microstructure depends on random physical factors … Visa mer Over 40 types of PUF have been suggested. These range from PUFs that evaluate an intrinsic element of a pre-existing integrated electronic system to concepts that involve explicitly introducing random particle distributions to the surface of physical … Visa mer In 2011, university research showed that delay-based PUF implementations are vulnerable to side-channel attacks and recommends that … Visa mer Optical PUFs rely on a random optical multiple-scattering medium, which serves as a token. Optical PUFs offer a promising approach to developing entity authentication schemes that are robust against many of the aforementioned attacks. However, … Visa mer Webb11 jan. 2024 · As relatively unbreakable identifiers, physical(ly) unclonable functions (PUFs), which are non-algorithmic one-way functions composed of uncopiable elements, have been extensively highlighted 10,11.

A fundamental difference between the traditional techniques and PUFs is that PUFs are, by nature, immune to reverse engineering techniques.
Physical unclonable function (PUF), sometimes also called physically unclonable function, is a physical entity that is embodied in a physical structure and is easy to evaluate but hard to predict. All PUFs are subject to environmental variations such as temperature, supply voltage and electromagnetic interference, which can affect their performance. Therefore, rather than just being random, the real power of a PUF is its ability to be different between devices, but simultan…
