Abstract

Silicon physical unclonable functions (sPUFs) exploit manufacturing process variations of semiconductor integrated circuits (ICs) to protect IoT-based devices from new cyberattacks. In this paper, a novel security technique, namely, an efficient lightweight configurable-based ring oscillator PUFs (c-ROPUFs)design, is proposed to enhance IoT-based reliability. The c-ROPUF is a low area design, mapped in a single CLB, and easy to implement on reconfigurable hardware. Data samples are collected under varying temperatures and supply voltage over a population of 30 Spartan-3E FPGA chips. The reliability ofc-ROPUF is identified and evaluated based on the standards of the International Organization for Standardization (ISO) in terms of reliability. With the application of the proposed 1-out-of-encoding algorithm, our results demonstrate that c-ROPUF shows magnified average reliability of 99.63% as compared to earlier PUF designs. Finally, the results also show that the c-ROPUFdesign is immune from accelerated aging impacts with no bitflip, leading to reliability issues.
