Techniques for design and implementation of physically unclonable functions
Physically unclonable functions (PUFs) provide a basis for many security, and digital rights management protocols. PUFs exploit the unclonable and unique manufacturing variability of silicon devices to establish a secret. However, as we will demonstrate in this work, the classic delay-based PUF …

A system for multi-level authentication with physically unclonable functions
We analyze deficiencies in existing Physically Unclonable Function (PUF) systems and protocols, and propose a new system of PUFs (SoP) that is numerically secure under extended attacker privileges and attack scenarios. Our proposed system uses a multi-level authentication scheme and employs …

Optimization of Physical Unclonable Function Protocols for Lightweight Processing
Physically unclonable functions are increasingly used as security primitives for device identification and anti-counterfeiting. However, PUFs are associated with noise and bias which in turn affects its property of reliability and predictability. The noise is corrected using fuzzy extractors, but …

Increasing the bit density of a quantum confinement physically unclonable function
… study the recently proposed quantum confinement physically unclonable function by Roberts, et al. that utilises resonant tunnelling diodes (physical representation of a quantum well) and atomic scale imperfections for applications in cryptography and identification. Presently such entities rely …

Entropy Estimation for Arbiter PUF and Applications to Authenticated Key Exchange
Physically Unclonable Functions (PUF) are hardware-based security primitives whose unique challenge and response behavior serves as a "fingerprint" for device authentication, key generation, and anti-counterfeiting. Modeling and estimating the entropy of PUF responses to random challenges is the …

Characterizing Retention behavior of DDR4 SoDIMM
… DRAM attribute can be considered a source of 'Physically Unclonable Functions' and is sought after in the Cryptography domain. This thesis aims to characterize the decay patterns of commercial DDR4 DRAM modules. I implemented a custom System On Chip on AMD/Xilinx's ZCU104 FPGA platform to …

APUF Faults: Testing, Diagnosing, and Salvaging
Arbiter Physically Unclonable Functions (APUFs) are hardware security primitives that generate unique digital fingerprints for integrated circuits (ICs) by exploiting manufacturing randomness. Ideally, a good APUF production line is characterized by symmetry, or equal delay for each track pair from …

Using imperfect semiconductor systems for unique identification
… systems are known as Unique Objects (UNOs) and Physically Unclonable Functions (PUFs). The aim of the work in this thesis is to create a novel type of UNO/PUF that utilises the atomic‐scale uniqueness of semiconductor devices by measuring a macroscopic quantum property of the system. The …
