Abstract
A method is used to reliably provision and re-generate a finite and exact sequence of bits, for use with cryptographic applications, e.g., as a key, by employing one or more challengeable Physical Unclonable Function (PUF) circuit elements. The method reverses the conventional paradigm of using public challenges to generate secret PUF responses; it exposes the response and keeps the particular challenges that generate the response secret.
