Abstract
A multi-port PUF circuit based on MOSFET current division deviations comprises a reference source, a row decoder, a column decoder, a timing controller and 32 PUF arrays. Each PUF array comprises 512 PUF cells arranged in 128 rows and 4 columns, an arbiter, a 1inverter, a 2inverter, a 3inverter, a 4inverter and eight transmission gates. The reference source is connected to the PUF arrays. The moutput terminal of the row decoder is connected to the mrow selective signal input terminals of the 32 PUF arrays. The joutput terminal of the column decoder is connected to the jselective signal input terminals of the 32 PUF arrays. The 1output terminal of the timing controller is connected to the control terminal of the row decoder. The 2output terminal of the timing controller is connected to the control terminal of the column decoder. The multi-port PUF circuit has the advantages of small circuit area and low power consumption while ensuring circuit performance.
