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

A Flip-Flop Based Arbiter Physical Unclonable Function (APUF) Design with High Entropy and Uniqueness for FPGA Implementation
TL;DR: Initial tests show that to attack the proposed FF-APUF design requires more effort for the adversary than a conventional APUF design, and the empirical min-entropy of the FF-apUF design across different devices is shown to be more than twice that of the conventional APF design.

A novel RFID distance bounding protocol based on physically unclonable functions
TL;DR: In this paper, a strong adversary model for Physically Unclonable Functions (PUF) based authentication protocol in which the adversary has access to volatile memory of the tag was introduced.

A Robust SRAM-PUF Key Generation Scheme Based on Polar Codes
TL;DR: This work proposes a practical error correction construction for PUF-based secret generation that are based on polar codes, and proposes an adaptive list decoder for polar codes that makes use of the hash that is already available at the decoder.

SIMPL systems, or: can we design cryptographic hardware without secret key information?
TL;DR: No secret information is, or needs to be, contained in SIMPL systems in order to enable cryptographic protocols -- neither in the form of a standard binary key, nor as secret information hidden in random, analog features, as it is the case for PUFs.

T2FA: Transparent Two-Factor Authentication
TL;DR: A transparent two-factor authentication (T2FA) based on physical unclonable function (PUF) and voiceprint that avoids the tedious interaction and provides the same high user experience satisfaction as the single-Factor authentication and exhibits high security simultaneously.

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.
