Enhancing virtual physically unclonable function security through neuron-criticality analysis and lightweight encryption [PDF]

Scientific Reports
Physically unclonable functions (PUFs) have long been a key component of hardware-based device authentication. They rely on intrinsic manufacturing variability to give unique and tamper-resistant Identifiers for each silicon device.

Food-Grade Physically Unclonable Functions. [PDF]

ACS Appl Mater Interfaces, 2023
Counterfeit products in the pharmaceutical and food industries have posed an overwhelmingly increasing threat to the health of individuals and societies. An effective approach to prevent counterfeiting is the attachment of security labels directly on drugs and food products.

Oscillator Selection Strategies to Optimize a Physically Unclonable Function for IoT Systems Security

Sensors, 2023
Physically unclonable functions avoid storing secret information in non-volatile memories and only generate a key when it is necessary for an application, rising as a promising solution for the authentication of resource-constrained IoT devices. However,
