Abstract
According to embodiments of the present invention are systems and methods for using scan chains for the creation of unique physically uncloneable function (PUF). In particular, the present invention uses existing circuitry on an integrated circuit and the internal-scan or boundary-scan register to create a unique identifier for each integrated chip. The unique nature of the scan chains results from the inherent variability of the manufacturing process.
