Physical Unclonable Function based Design for Customized Digital Logic Circuit

Abstract

Security, area and energy efficient primitives are the fundamental blocks for empowering end-to-end contented protection in Integrated circuits (ICs). PUF is similar physical security effervescent, which uses in-deterministic dissimilarities in the course of manufacturing process, to produce a distinctive and an unclonable IC. In this paper, a digital real time delay based Intrinsic RO-PUF has been proposed to design and detect an input challenge to authenticate and to generate a response. RO-PUF design is implemented on DigilentNexys 2 FPGA and Spartan-3E FPGA boards. The PUF design is validated by means of external evaluation on FPGA by interfacing peripherals like VGA, LCD and SSD to external GPIO modules.
