Information-theoretic analysis of capacitive physical unclonable functions
Physical unclonable functions PUFs can be used as a cost-effective means to store cryptographic key material in an unclonable way. In coating PUFs, keys are generated from capacitance measurements of a coating containing many randomly distributed particles with different dielectric constants. We introduce a physical model of coating PUFs by simplifying the capacitance sensors to a parallel plat...

11:00 6.2.1 EFFICIENT ATTACKS ON ROBUST RING OSCILLATOR PUF WITH ENHANCED CHALLENGE-RESPONSE SET (Paper/SoftConf ID: 699) Speakers: Phuong Ha Nguyen, Durga Prasad Sahoo, Rajat Subhra Chakraborty and Debdeep Mukhopadhyay, Indian Institute of Technology Kharagpur, IN Abstract Physically Unclonable Function (PUF) circuits are an important class of hardware security primitives that promise a paradi...
متن کاملPUF – Physical Unclonable Functions
from historical banking and telecommunication applications to electronic passports, electronic IDs, anti-counterfeiting devices, smartgrid applications, and more. The security requirements for most of these applications are crucial and evolving. In addition, more and more sophisticated attacks are being developed every day. As a result, design of Smart Card ICs is a growing challenge. This pape...
متن کاملRecombination of Physical Unclonable Functions
A new Physical Unclonable Function (PUF) construction is described, by treating silicon unique features extracted from PUF circuits as “genetic material” unique to each silicon, and recombining this chip-unique material in a way to obtain a combination of advantages not possible with the original PUF circuits, including altering PUF output statistics to better suit PUF-based key generation and ...
متن کاملRevisiting Optical Physical Unclonable Functions
We revisit optical physical unclonable functions (PUFs), which were introduced by Pappu et al. [36, 37] in their seminal and historically first publication on PUFs. We start our studies with non-integrated PUFs. We discuss their resilience against machine learning attacks, and systematically study the influence of using more than one laser beam, varied laser diameters, and smaller scatterer siz...
