Physical Unclonable ID/Key
Physical Unclonable ID/Key
PUFs are usually utilized in cryptography. A physical unclonable function (sometimes also called physically unclonable function) is a physical entity that is embodied in a physical structure. Today, PUFs are usually implemented in integrated circuits and are typically used in applications with high security requirements. The chip's unique birthmark iUnique technology is based on the physical non-cloning technology PUF, which uses the random characteristics of each chip to generate a random key or security ID, which is the "fetal birthmark" unique to each chip, and addresses the root of trust of the system.
