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

Lightweight and Secure PUFs: A Survey (Invited Paper)
TL;DR: In this paper, all existing designs for lightweight PUF are studied and the implementation and security analysis of those designs are discussed.

Defense Mechanisms against Machine Learning Modeling Attacks on Strong Physical Unclonable Functions for IOT Authentication: A Review
TL;DR: There is a need to design the best defense mechanism which is not only resistant to ML-MA but also produces reliable responses and reduces area overhead, and the Physical Unclonable Function (PUF) is suggested to replace crypto module for IoT authentication.

A dynamically configurable LFSR-based PUF design against machine learning attacks
TL;DR: A lightweight composition PUF design, Shift Register based PUF (SRPUF), is proposed in which the time delay performance is sacrificed to make the PUF structure variable and difficult to derive a stable model.

Session Key Derivation for Low Power IoT Devices
TL;DR: A candidate key derivation function for low power IoT device keys is presented, enabling the generation of a stream of session keys from a larger base key, allowing for a reasonably robust private key cryptographic infrastructure suitable to low power reduced precision systems.

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.
