Security enhancement of arbiter-based physical unclonable function on FPGA

Abstract

In order to reduce physical unclonable function (PUF) response instability and imbalance caused by the metastability and the bias of arbiter, this paper uses an improved balanced D flip-plop (DFF) based on the unbalanced DFF to reduce the bias in response output and enhances the security of PUF by adopting two balanced DFFs in series. The experimental… (More)
