Physical Unclonable Function (PUF)

Q: What is Physical Unclonable Function?

A Physical Unclonable Function (PUF) is a hardware security primitive that derives unique, device-specific digital responses from uncontrollable manufacturing variations in physical circuits, which security systems use as a source of identifiers, secrets, or cryptographic keys. Expanded Explanation 1. Technical Function and Core Characteristics A PUF maps a digital challenge input to a digital response that depends on the microscopic physical characteristics of a specific hardware instance.

Physical Unclonable Function is a hardware security primitive that uses uncontrollable manufacturing variations to derive device-unique digital responses, enabling hardware root of trust, anti-counterfeiting, and key generation without storing long-term secrets in nonvolatile memory in enterprise and embedded systems.
