Webb8 juni 2007 · Physical Unclonable Functions (PUFs) are innovative circuit primitives that extract secrets from physical characteristics of integrated circuits (ICs). We present PUF designs that exploit inherent delay characteristics of wires and transistors that differ from chip to chip, and describe how PUFs can enable low-cost authentication of individual ICs … 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 … 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 … 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 … Visa mer • PUF technology can be licensed from several companies including eMemory, or its subsidiary, PUFsecurity, Enthentica, ICTK, Intrinsic ID, Invia, QuantumTrace, Granite Mountain Technologies and Verayo. • PUF technology has been implemented in … Visa mer
