AbstractSo-called "Physical Unclonable Functions" (PUFs) can help us to achieve a high level of security in a number of basic security primitives such as identification, authentication, tamper resistance, anti-counterfeiting and secure key storage.
A PUF is a complex physical structure that is hard to clone, where cloning means both (i) making a physical copy and (ii) making an accurate mathematical model of the structure. The word "function" refers to the fact that the structure responds to stimuli like a one-way function.
The study of PUFs gives rise to a unique combination of statistical physics, information theory, coding theory and (asymmetric) cryptography.
The talk explains how these subjects come together when one constructs a PUF-based Zero Knowlewdge authentication system.
