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

Robustness Analysis of a Memristive Crossbar PUF Against Modeling Attacks
TL;DR: This work describes the operation of a memristive crossbar based PUF that generates response bits as a function of variable memristor switching time and considers its resilience to two specific machine learning attacks, specifically through the use of linear regression and support vector machines.

Breaking through fixed PUF block limitations with differential sequence coding and convolutional codes
TL;DR: This work presents a new syndrome coding scheme, called Differential Sequence Coding (DSC), for the first error correction stage of PUFs, and is the first to propose a convolutional code with Viterbi decoder as second stage error correction for PUFs.

A high reliability PUF using hot carrier injection based response reinforcement
Mudit Bhargava,Ken Mai +1 more
TL;DR: This work presents a PUF response reinforcement technique based on hot carrier injection (HCI) which can reinforce the PUF golden response in short stress times, without impacting the surrounding circuits, and that has high permanence (i.e., does not degrade significantly over aging).

SIMPL Systems: On a Public Key Variant of Physical Unclonable Functions.
TL;DR: In this article, the authors theoretically discuss a novel security tool termed SIMPL system, which can be regarded as a public key version of physical unclonable functions (PUFs).

Dynamic memory-based physically unclonable function for the generation of unique identifiers and true random numbers
TL;DR: It is shown that DRAM can be used as a physically unclonable function and in contrast to SRAM-based PUF, DRAM PUF allow for repeated operations without disconnecting supply voltage while still remaining fully functional for normal storage operations.

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.
Proceedings ArticleDOI
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.
