Abstract
In this chapter, we first review the definition of an ideal Physically Unclonable Function (PUF) and explore the functionality of two popular delay-based PUFs, namely Arbiter PUF and ring-oscillator (RO) PUF. Second, we study the internal architecture of reconfigurable hardware and discuss the security issues of FPGAs during configuration. Moreover, we survey the PUF implementations on these platforms. Afterward, we review the optical semi-invasive techniques, which are used in this work to attack PUF implementations on reconfigurable hardware.
