Abstract

Physically Unclonable Functions have gained significant attention in recent years for their ability to address hardware security concerns. This work presents a method to implement ring oscillator-based PUF on the FPGA platform. Specifically, an 11-order oscillation ring is configured by cascading inverters, exploiting the little variations in the FPGA manufacturing process to generate unpredictable, random output. To evaluate the proposed structure, experiments were conducted using the Xilinx Kintex-7 FPGA chip. The experimental results demonstrate that the designed RO-PUF exhibits a uniformity of 47.30%, uniqueness of 47.46%, and reliability of 97.07%. It possesses several advantages, including ease of implementation, minimal resource utilization, and the elimination of manual layout and routing requirements.
