ABSTRACT:
If no encryption key necessary for performing encrypted communication to opposite communication terminal6exists, subscriber terminal5transmits key exchange proxy request message to service control unit1. The service control unit1transfer the key exchange proxy request to key exchange proxy server2based on service profile transmitted from authentication server3. The key exchange proxy server2decides key by transmitting/receiving key exchange message to/from the opposite communication terminal6. A message including the decided key is transmitted to the service control unit1. The service control unit transfer the message from the key exchange proxy server2with the key to the subscriber terminal5based on the service profile. Then, encrypted communication between the subscriber terminal5and the opposite communication terminal6is performed.
