Abstract
When an AAAh server in a home domain receives an authentication request message from an mobile IP terminal in a visited domain, the AAAh server transmits a secret key generated by a secret key generating unit to an AAAv server in the visited domain and to the mobile IP terminal. Consequently, an authority to authenticate the mobile IP terminal is assigned from the AAAh server in the home domain to the AAAv server in the visited domain. When the AAAv server receives an authentication request from the mobile IP terminal, the AAAv server directly performs the authentication without exchanging messages with the AAAh server.
