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.

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,
