Physically Unclonable Functions
Physically Unclonable Functions (PUFs) act as a 'digital fingerprint' for hardware devices. They leverage inherent, random physical variations introduced during the semiconductor manufacturing process to create unique, unclonable cryptographic keys. This technology is critical for device authentication, anti-counterfeiting, and secure boot processes, providing a hardware root of trust that is extremely difficult to replicate.
