TLDR
This work presents PUF designs that exploit inherent delay characteristics of wires and transistors that differ from chip to chip, and describes how PUFs can enable low-cost authentication of individual ICs and generate volatile secret keys for cryptographic operations.Abstract:
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 and generate volatile secret keys for cryptographic operations.read more

Security Based on Physical Unclonability and Disorder
TL;DR: This chapter provides a classification for past and ongoing work in physical disorder based security alongside with security analyses and implementation examples and outlines some open problems and future research opportunities.

FPGA PUF using programmable delay lines
TL;DR: A high resolution programmable delay logic (PDL) implemented by lookup table (LUT) internal structure is introduced, and fine tuning is performed to cancel out delay skews caused by asymmetries in routing and systematic variations.

A Lockdown Technique to Prevent Machine Learning on PUFs for Lightweight Authentication
Meng-Day (Mandel) Yu,Matthias Hiller,Jeroen Delvaux,Richard Sowell,Srinivas Devadas,Ingrid Verbauwhede +5 more
TL;DR: This work presents a system-level approach that allows a so-called strong PUF to be used for lightweight authentication in a manner that is heuristically secure against today's best machine learning methods through a worst-case CRP exposure algorithmic validation.

Physical one-way functions
TL;DR: The concept of fabrication complexity is introduced as a way of quantifying the difficulty of materially cloning physical systems with arbitrary internal states as primitives for physical analogs of cryptosystems.

Silicon physical random functions
TL;DR: It is argued that a complex integrated circuit can be viewed as a silicon PUF and a technique to identify and authenticate individual integrated circuits (ICs) is described.
Tamper resistance: a cautionary note
Ross Anderson,Markus G. Kuhn +1 more
TL;DR: It is concluded that trusting tamper resistance is problematic; smartcards are broken routinely, and even a device that was described by a government signals agency as 'the most secure processor generally available' turns out to be vulnerable.

Extracting secret keys from integrated circuits
TL;DR: It is shown that arbiter-based PUFs are realizable and well suited to build key-cards that need to be resistant to physical attacks and to be identified securely and reliably over a practical range of environmental variations such as temperature and power supply voltage.

Impact of die-to-die and within-die parameter fluctuations on the maximum clock frequency distribution for gigascale integration
TL;DR: In this paper, a model describing the maximum clock frequency distribution of a microprocessor is derived and compared with wafer sort data for a recent 0.25-/spl mu/m microprocessor.
