Abstract
An attack detection device includes: a receiver configured to receive a massage that includes target identification information transmitted in a network; and a processor. The processor predicts a number of massages to be received by the receiver in a specified monitor period based on a transmission cycle so as to generate a predicted value. The processor counts a number of massages received by the receiver in the monitor period so as to generate a count value. When the count value is larger than the predicted value and smaller than or equal to a reference value that is obtained by adding an early-arrival acceptable value to the predicted value, the processor decides whether the network has been attacked according to a result of a comparison between the predicted value and the count value after an early-arrival grace period corresponding to the early-arrival acceptable value elapses.
