Abstract
A monitoring device is configured to monitor a monitoring target device. The monitoring device includes a circuit information distribution program configured to distribute circuit information for programming a physically unclonable function (PUF) circuit to the monitoring target device; a transmission processing program configured to transmit a challenge value to the monitoring target device to which circuit information is distributed; a reception processing program configured to receive a response value corresponding to the challenge value of the PUF circuit programmed in the monitoring target device; and an authentication processing program configured to authenticate the monitoring target device based on input and output correspondence information of the PUF circuit programmed in the monitoring target device and the response value which has been received.
