Analysis and Evaluation of PUF-Based SoC Designs for Security Applications

This paper presents a critical analysis and statistical evaluation of two categories of physically unclonable functions (PUFs): ring oscillator PUF and a new proposed adapted latch-based PUF. The main contribution is that of measuring the properties of PUF which provide the basic information for using them in security applications. The original method involved the conceptual design of adapted latch-based PUFs and ring oscillator PUFs in combination with peripheral devices in order to create an environment for experimental analysis of PUF properties. Implementation, testing, and analysis of results followed. This approach has applications on high-level security.
