A Lightweight Configurable XOR RO-PUF Design Based on Xilinx FPGA

Lightweight electronic devices are emerging as a promising electronic equipment. Physical unclonable function (PUF), a kind of authentication circuit in lightweight electronic chip, is very useful component in secure system design. The reliability and uniqueness of PUF is limited by the complexity of its circuit. Herein, a reconfigurable XOR gate PUF based on configurable delay line is demonstrate...
