Design Guidelines and Feedback Structure of Ring Oscillator PUF for Performance Improvement

IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems
The physical unclonable function (PUF) is a hardware security primitive that is used to generate secret keys or identity authentication for chips using random manufacturing process variation (MPV).

A Weak PUF-Assisted Strong PUF With Inherent Immunity to Modeling Attacks and Ultra-Low BER

IEEE Transactions on Circuits and Systems Part 1: Regular Papers, 2022
This paper presents a weak PUF-assisted strong PUF that combines the metrics between weak and strong PUFs. Unlike the conventional strong PUFs that rely on the nonlinear combination of a large number of entropy cells for high modeling attacks resilience,

Fully Symmetrical Obfuscated Interconnection and Weak-PUF-Assisted Challenge Obfuscation Strong PUFs Against Machine-Learning Modeling Attacks

IEEE Transactions on Information Forensics and Security
In this paper, we propose a fully symmetrical obfuscated-interconnection PUF (SOI PUF), which contains $n$ delay stages with each stage having $4k$ obfuscated interconnections for resisting machine learning (ML)-based modeling attacks.

SI PUF: An SRAM and Inverter-Based PUF With a Bit Error Rate of 0.0053% and 0.073/0.042 pJ/bit

IEEE Transactions on Circuits and Systems - II - Express Briefs
The physical unclonable function (PUF) can generate a unique identifier for each chip, ideal for key generation and chip anti-counterfeiting. The reliability of PUF is paramount, and therefore is one of the significant challenges for PUF design.

MRAM PUF

ACM Journal on Emerging Technologies in Computing Systems, 2016
In this work, we have studied two novel techniques to enhance the performance of existing geometry-based magnetoresistive RAM physically unclonable function (MRAM PUF). Geometry-based MRAM PUFs rely only on geometric variations in MRAM cells that generate preferred ground state in cells and form the basis of digital signature generation.

PUF ROKs

Proceedings of the 6th ACM Symposium on Information, Computer and Communications Security, 2011
Cryptographers have proposed the notion of read-once keys (ROKs) as a beneficial tool for a number of applications, such as delegation of authority. The premise of ROKs is that the key is destroyed by the process of reading it, thus preventing subsequent accesses.

D-PUF

Proceedings of the International Conference on Compilers, Architectures and Synthesis for Embedded Systems, 2016
Physically Unclonable Functions (PUFs) have proved to be an effective and low-cost measure against counterfeiting by providing device authentication and secure key storage services. Memory based PUF implementations are an attractive option due to the ubiquitous nature of memory in electronic devices and the requirement of minimal (or no) additional ...
