An Anti-interference Design based on Glitch PUF

Physical Unclonable Function (PUF) provides a new solution for information security. In this paper, the output of Glitch PUF are sampled under different operating voltages. Our experiments prove that the voltage fluctuation can affect the performance of PUF. In view of the defect of output flip of Glitch PUF caused by interference, this paper first verifies the influence of this output defect on the security of PUF, and then proposes an improved structure design to improve anti-interference ability of Glitch PUF.
