Abstract
A search part sends out a connection request signal and receives a connection response signal. A radio strength acquiring part acquires radio strength of an available device that has sent the connection response signal. A connection determining part determines whether or not the radio strength has increased, then becomes greater than or equal to a threshold value and has been constant for a period of time longer than or equal to a predetermined period of time. If it is determined that the radio strength has increased, then becomes greater than or equal to the threshold value and has been constant for a period of time longer than or equal to the predetermined period of time, an inter-device authentication part performs inter-device authentication with the available device.
