Design and Verification of Dynamic Reconfigurable ROPUF Based on XOR Gate
This paper describes that there are four main research directions of Physical Unclonable Function(PUF)technology,such as new structure,response error correction,security and application.It focuses on the circuit structure of reconfigurable physical unclonable technology,which belongs to a branch of PUF new structure research.In order to improve the robustness of the proposed ring oscillator physical unclonable functions(RO PUF),a physical unclonable function circuit based on XOR gate(XOR RO PUF)is proposed to verify the new physical unclonable functions.It is necessary to improve the effectiveness of PUF.With the help of FPGA tools,the physical unclonable function circuit of the reconfigurable ring oscillator based on XOR gate is analyzed on several Xilinx XCVU440 of the same model.Compared with the traditional RO PUF,the reconfigurable ring oscillator based on XOR gate is more efficient.The physical unclonable function circuit of RO shows higher inter chip Hamming distance and lower intra chip Hamming distance.
