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

Circuit and method for generating a true, circuit-specific and time-invariant random number
TL;DR: In this article, the authors proposed a method for generating a true, circuit-specific and time-invariant random number by means of a matrix of L-K delay elements, L-1 single or double commutation circuits, a single-or double demultiplexer connected before the matrix, and a double multiplexer connection after the matrix.
Using physical unclonable functions for hardware authentication: a survey
TL;DR: This work tries to establish one organization of existing PUF structures, giving guidelines for their choice, conditioning, and adaptation depending on the target application, and how using PUFs adequately could enlighten significantly most of the security primitives.

Digital PUF using intentional faults
Teng Xu,Miodrag Potkonjak +1 more
TL;DR: This paper proposes the concept of digital PUF where the core idea is to intentionally use high-risk synthesis to induce defects in circuits to guarantee the fault-baseddigital PUF resilient against operational variations.

Methods and apparatus to create a physically unclonable function
TL;DR: In this paper, a physically unclonable function for SRAM is presented. But the function is not defined, it is only defined when the memory array is operating at a voltage level above the first voltage level.
Patent
Radio frequency identification technology incorporating cryptographics
TL;DR: In this article, a radio frequency identification (RFID) tag comprising an RFID functional portion configured to enable wireless communication between the RFID tag and an RPN reader, a data processing functional portion with asymmetric cryptographic capability, and a power source was presented.

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.
