Topic: Physical Unclonable Functions (PUFs)

A physical unclonable function, or PUF, is a "digital fingerprint" that serves as a unique identity for a semiconductor device such as a microprocessor. PUFs are based on physical variations which occur naturally during semiconductor manufacturing, and which make it possible to differentiate between otherwise identical semiconductors. 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.

Information Assurance (IA) is the application of this directive in the cyber domain. IA activities include measures that protect and defend information and information systems by ensuring their availability, integrity, authentication, confidentiality, and non-repudiation. IA is the practice of assuring information and managing risks related to the use, Read More
