Ring Oscillator-Based Physical Unclonable Functions

Unleashing the power of colloidal gold immunochromatographic assays for plant virus diagnostics

“…Alanine Scanning: In this approach, specific amino acids within the antigen are mutated to alanine, and the effect on antibody binding is assessed. This helps pinpoint critical epitopes [60] .…”

Physical Unclonable Function Based on the Internal State Transitions of a Fibonacci Ring Oscillator

“…Due to their ease of deployment, RO PUFs are often the preferred form of FPGA-based solutions [ 9 ]. In these PUFs, the differences between frequencies of multiple ring oscillators of the same structure are typically used to generate a unique PUF response [ 9 , 10 ]. In prior studies, several approaches based on ring oscillators have been proposed and have achieved success in the generation of secure keys.…”
