1. A method of establishing, by an image forming apparatus, a connection to a mobile device, the method comprising:
- transmitting temporary credential information to the mobile device in response to receiving a pairing request from the mobile device;
receiving an encrypted personal identification number (PIN) code from the mobile device, wherein a PIN code input by a user of the mobile device was encrypted by the mobile device to produce the encrypted PIN code using the temporary credential information;
determining, by the image forming apparatus, whether the PIN code is valid by decrypting the encrypted PIN code using the temporary credential information to extract the PIN code; and
transmitting permanent credential information to the mobile device when it is determined that the PIN code is valid.

11. A method of establishing, by a mobile device, a connection to an image forming apparatus, the method comprising:
-
receiving temporary credential information issued by the image forming apparatus in response to transmitting a pairing request to the image forming apparatus; generating an encrypted personal identification number (PIN) code by encrypting, using the temporary credential information, a PIN code input by a user; transmitting the encrypted PIN code to the image forming apparatus; and receiving permanent credential information from the image forming apparatus when the image forming apparatus determines that the PIN code is valid, wherein the image forming apparatus extracts the PIN code from the encrypted PIN code. - View Dependent Claims (12, 13, 14, 15, 16)

17. An image forming apparatus for establishing a connection with a mobile device, the image forming apparatus comprising:
-
a communicator configured to transmit to the mobile device temporary credential information issued in response to receiving a pairing request from the mobile device, and to receive an encrypted personal identification number (PIN) code from the mobile device; and a main controller configured to determine whether a PIN code is valid by decrypting the encrypted PIN code using the temporary credential information, the PIN code having been input by a user of the mobile device and encrypted by the mobile device to produce the encrypted PIN code using the temporary credential information, wherein the main controller is configured to issue permanent credential information when it is determined that the PIN code is valid, and the communicator is configured to transmit the permanent credential information to the mobile device. - View Dependent Claims (18, 19, 20)
