Abstract: A public key of a sensor node key pair is transmitted from a sensor node 22 to a server 20 via sensor network communication, and furthermore is transmitted from the server 20 to a mobile terminal 25 via mobile line communication. In addition, a public key of a mobile terminal key pair is transmitted from the mobile terminal 25 to the sensor node 22 through local communication. Thus, the configuration allows the sensor node 22 and the mobile terminal 25 to generate a common key by combining their own private key and the public key of the counterpart in order to encrypt the local communication by using this common key.
