Abstract
Provided are a method and apparatus for establishing communication via a service provider providing a service of establishing communication between a transmitting terminal and a receiving terminal. The method includes receiving an encryption key from the service provider, transmitting the encryption key to an external device storing receiving terminal identification information required for establishing communication with the receiving terminal, receiving the encrypted receiving terminal identification information from the external device, and transmitting the encrypted receiving terminal identification information to the service provider.
Claims26
A method of establishing communication via a service provider providing a service of establishing communication between a transmitting terminal and a receiving terminal, the method comprising:
- receiving at the transmitting terminal an encryption key from the service provider;
- transmitting the encryption key from the transmitting terminal to an external device, the external device storing receiving terminal identification information required for establishing communication with the receiving terminal;
- receiving at the transmitting terminal the encrypted receiving terminal identification information from the external device in response to the transmitted encryption key;
- and
- transmitting the encrypted receiving terminal identification information from the transmitting terminal to the service provider.
A method of transmitting receiving terminal identification information, required for establishing communication between a transmitting terminal and a receiving terminal, the method comprising:
- receiving an encryption key at an external device transmitted from the transmitting terminal;
- encrypting at the external device the receiving terminal identification information using the received encryption key;
- and
- transmitting the encrypted receiving terminal identification information from the external device to the transmitting terminal.
A device for establishing communication via a service provider providing a service of establishing communication between a transmitting terminal and a receiving terminal, the device comprising:
- a receiving unit receiving an encryption key from the service provider;
- and
- a transmitting unit transmitting the encryption key to an external device, the external device storing receiving terminal identification information required for establishing communication with the receiving terminal,
- wherein the receiving unit receives encrypted receiving terminal identification information from the external device encrypted at the external device using the transmitted encryption key, and the transmitting unit transmits the received encrypted receiving terminal identification information to the service provider.
An external device including a receiving terminal identification information transmitting terminal transmitting receiving terminal identification information required for establishing communication between a transmitting terminal and a receiving terminal, the external device comprising:
- a receiving unit receiving an encryption key from the transmitting terminal;
- an encrypting unit encrypting the receiving terminal identification information stored within the external device using the received encryption key;
- and
- a transmitting unit transmitting the encrypted receiving terminal identification information to the transmitting terminal.
A method of establishing communication between a transmitting terminal and a receiving terminal using an external device, the method comprising:
- receiving from the transmitting terminal encrypted receiving terminal identification information encrypted by the external device using an encryption key transmitted from the transmitting terminal to the external device;
- decrypting the encrypted receiving terminal identification information using the encryption key;
- and
- establishing a communication link between the transmitting terminal and the receiving terminal using the decrypted receiving terminal identification information.
