Uniformity
This dataset contains Challenge-Response Pairs (CRPs) from Ring Oscillator-based Physical Unclonable Functions (RO-PUFs) operating under constant and variable voltage conditions. Collected from three chips fabricated in a 22nm FDSOI process and powered by a Switched-Capacitor DC-DC converter, it includes two sections: responses at a fixed voltage and across nine voltage levels (nominal and ±10% variations). Organized into ten folders, the dataset includes 1K CRPs per chip for each voltage and a combined folder with 20K CRPs.

Securing systems with limited resources is crucial for deployment and should not be compromised for other performance metrics like area and throughput. Physically Unclonable Functions (PUFs) emerge as a cost-effective solution for various security applications, such as preventing IC counterfeiting and enabling lightweight authentication. In the realm of memory-based PUFs, the physical variations of available memory systems, such as DRAM or SRAM, are exploited to derive an intrinsic response based on the accessed data row.

This data set corresponds to Table II:UNIFORMITY OF TC-PUF DESIGN of manuscript titled "A Lightweight and Secure Physical Unclonable Function Design on FPGA". The provided data is for FPGA board No. 1 to 15. Board no. 1 to 14 represent uniformity of 40X40 TC-PUF response implemented on Artix-7 FPGA, and board no. 15 represent uniformity of 20X40 TC-PUF response implemented on Zynq Z-7010 FPGA. It is observed that nearly all the TC-PUF implemented on individual FPGAs have a slight bias towards ‘0’.
