Description
Summary: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 results show that two cascaded balanced DFFs improve the stability of the DFF,and the output of two balanced DFFs is more reliable. The entropy of output is fixed at 98.7%.
