Reader-friendly Edible Binarycodes and Sensors Based on Smart Hydrogel

Food and medicines are two of the most essential categories of goods for human beings, providing vital nourishment and healthcare. However, as these products are commercialized and distributed on a global scale, consumers face the threat of counterfeit and deteriorated products. In response, this dissertation presents four prototypes consisting...

Biocompatible optical physically unclonable function hydrogel microparticles for on-dose authentication

On-dose authentication (ODA) enhances security by incorporating customized molecular or micro-tags into each pill, preventing counterfeit products in genuine packages. ODA's security relies on tag non-replication and non-reverse engineering. Combining ODA with graphical Physical Unclonable Functions (PUF) promises maximum security. PUF uses...

Experimental investigation and thermodynamic modelling of the ThF₄-PuF₃ phase diagram

Phase equilibria in the ThF₄-PuF₃ system were measured by differential scanning calorimetry. Samples were encapsulated to prevent leakage during the measurements and to prevent fluoride contamination of the instrument. Formation of intermediate compounds and solid solutions was investigated by X-ray diffraction. A...

Modeling and Analysis of SRAM PUF Bias Patterns in 14nm and 7nm FinFET Technology Nodes

SRAM Physical Unclonable Functions (PUFs) are one of the popular forms of PUFs that can be used to generate unique identifiers and randomness for security purposes. Hence, their resilience to attacks is crucial. The probability of attacks increases when the SRAM PUF start-up values follow a predictable pattern which we refer to as bias. In this...

Reliability Analysis of FinFET-Based SRAM PUFs for 16nm, 14nm, and 7nm Technology Nodes

SRAM Physical Unclonable Functions (PUFs) are among other things today commercially used for secure primitives such as key generation and authentication. The quality of the PUFs and hence the security primitives, depends on intrinsic variations which are technology dependent. Therefore, to sustain the commercial usage of PUFs for cutting-edge...

Exploiting PUF Variation to Detect Fault Injection Attacks

The massive deployment of Internet of Things (IoT) devices makes them vulnerable against physical tampering attacks, such as fault injection. These kind of hardware attacks are very popular as they typically do not require complex equipment or high expertise. Hence, it is important that IoT devices are protected against them. In this work, we...

Modeling Static Noise Margin for FinFET based SRAM PUFs

In this paper, we develop an analytical PUF model based on a compact FinFET transistor model that calculates the PUF stability (i.e. PUF static noise margin (PSNM)) for FinFET based SRAMs. The model enables a quick design space exploration and may be used to identify critical parameters that affect the PSNM. The analytical model is validated...

Enhancing PUF based challenge-response sets by exploiting various background noise configurations

Physically Unclonable Functions (PUFs) are a cryptographic primitive that exploit the unique physical characteristics of Integrated Circuits (ICs). A PUF can be modeled as a black-box challenge-response system. The number and size of challenge-response pairs (CRPs) supported by a PUF determine and condition its strength. Ring Oscillators (RO)...

Open-Source Software-Based SRAM-PUF for Secure Data and Key Storage Using Off-The-Shelf SRAM

SRAM PUF has a potential to become the main player in hardware security. Unfor- tunately, currently available solutions are usually locked to specific entities, such as companies or universities. Here, we introduce the first open source project to de- velop software-based SRAM PUF technology using off-the-shelf SRAM. We also present testing...

Design & development of public-key based authentication architecture for IoT devices using PUF

Secure communication has been paramount throughout history. Although in the early ages it was mainly found in niche applications such as the military and royal society, today it is an inevitable part of our daily lives. The recent rapid proliferation of Internet of Things (IoT), a diverse set of devices that are connected to the Internet,...
