  • the AP 101 receives the request signal and judges that the request signal includes the second identification information (S 704 ). Then, the AP 101 encrypts the communication parameter by using a secret key corresponding to the public key included in the request signal and provides the smartphone 103 with the encrypted communication parameter (S 705 ). Note that, the AP 101 does not register the smartphone 103 as the management apparatus (S 706 ). After that, connection processing of the AP 101 and the smartphone 103 is performed, and the smartphone 103 is connected to the wireless network 104 (S 707 ).
  • the smartphone 103 gives an addition instruction of the printer 106 (S 711 ).
  • the smartphone 103 requests the AP 101 to connect the printer 106 as the external apparatus to the wireless network 104 .
  • the smartphone 103 transmits an addition request signal to the AP 101 (S 712 ).
  • the AP 101 When receiving the addition request signal, the AP 101 checks whether the smartphone 103 is registered as the management apparatus (S 713 ). Since the smartphone 103 is not registered as the management apparatus here, the AP 101 transmits an addition rejection response to the smartphone 103 (S 714 ). When receiving the addition rejection response, the smartphone 103 notifies the user of an error. Then, the AP 101 ends the processing without providing the printer 106 with the communication parameter, that is, in a state of non-providing.
  • the smartphone 103 may be prevented from selecting the addition instruction itself of the external apparatus. This makes it possible to enhance user convenience.
  • the AP 101 may be disconnected from the smartphone 103 or may not communicate with the smartphone 103 for a predetermined time.
  • the smartphone 102 transmits the request signal of the communication parameter including first or second identification information to the AP 101 .
  • first or second identification information is not included in the request signal of the communication parameter and a signal different from the request signal is used to transmit the first or second identification information to the AP 101 .
  • the AP 101 when receiving the request signal of the communication parameter including the second identification information from the smartphone 103 , the AP 101 does not register the smartphone 103 as the management apparatus.
  • an attribute indicating that the smartphone 103 is not registered as the management apparatus may be stored in the storage unit 201 .
  • the AP 101 checks that the smartphone 103 is not registered as the management apparatus by referring to the attribute at step S 713 .
  • the setting of the network refers to setting of SSID which is a network identifier of the wireless network generated by the AP 101 , an encryption method, an encryption key, an authentication method, an authentication key, and the like.
  • the identification information of the smartphone providing the communication parameter at step S 411 of the aforementioned embodiment may be stored in association with a public key of the smartphone. Thereby, even when setting of the AP 101 is changed and the communication parameter is to be provided to the smartphone again, the communication parameter is able to be provided by encrypting the communication parameter with a public key of each smartphone, thus enhancing security.
  • the AP 101 encrypts the communication parameter by using the secret key corresponding to the pubic key included in the first or second identification information.
  • the communication parameter may be encrypted by using another key generated based on the public key or the secret key, such as hash of the public key or hash of the secret key.
  • the first or second identification information is included in the QR code® in the aforementioned embodiment.
  • the first or second identification information may be included in a one-dimensional bar code or other two-dimensional bar codes.
  • the identification information may be notified to the smartphone 102 by the AP 101 through wireless communication such as the NFC, the Bluetooth, the IEEE 802.11 ad, or the Transfer Jet.
  • the identification information in the aforementioned embodiment may be an identifier specific to a smartphone, for example, a MAC address.
  • a similar effect is able to be achieved by registering a MAC address which allows operation as a management apparatus in the AP 101 in advance.
  • aspects of the invention can also be realized by a computer of a system or apparatus to which a program for realizing one or more functions of the embodiment are supplied through a network or a storage medium and in which one or more processors thereof read and execute the program.
