A Combined Design of 4-PLL-TRNG and 64-bit CDC-7-XPUF on a Zynq-7020 SoC
Abstract
True Random Number Generators (TRNGs) and Physically Unclonable Functions (PUFs) are critical hardware primitives for cryptographic systems, providing randomness and device-specific security. TRNGs require complete randomness, while PUFs rely on consistent, device-unique responses. In this work, both primitives are implemented on a System-on-Chip Field-Programmable Gate Array (SoC FPGA), leveraging the integrated Phase-Locked Loops (PLLs) for robust entropy generation in PLLbased TRNGs. A novel backtracking parameter selection algorithm for the TRNG implementation is employed, alongside a methodology to boost data generation rates without compromising entropy. The design is rigorously evaluated using the German BSI AIS-20/31 standards. For the PUF implementation, the Arbiter PUF, known for its lightweight design and key generation, is enhanced to resist machine learning attacks by implementing a 32-bit and a 64-bit component-differentially challenged XOR Arbiter PUF (CDC-XPUF). These designs are tested using standard PUF metrics, including uniformity, correctness, and uniqueness. Finally, a combined 4-PLL-TRNG and 64-bit CDC-XPUF design is introduced and evaluated for its suitability in Internet-of-Things (IoT) systems, demonstrating strong performance in both TRNG and PUF tests. The tests are conducted on the Xilinx Zynq 7020 SoC using a ZC702 evaluation board, confirming the effectiveness of this integrated approach for secure, low-resource applications like IoT.
