Technology

Physical Unclonable Functions (PUFs) for Hardware-Level Device Authentication

Quick fact

PUFs exploit the fact that no two chips are identical, even when manufactured with the same design, due to microscopic variations in the production process—these variations are so small that they are impossible to clone or replicate.

Why this is interesting

Imagine if every microchip had a unique, unalterable fingerprint hidden within its silicon. How could that fingerprint authenticate your devices without ever being digitally stored?
