A New Scheme for Unified-Authentication in BcN

There are many authentication mechanisms and authentication parameters. In the BcN (broadband convergence network), there is a strong requirement of unified authentication. Therefore, we propose a new authentication scheme especially for the BcN. The proposed scheme supports the authentication of a mobile node before the mobile node moves to a new access network. For this, an AAA core-broker is positioned in the core network and manages the information for the authentication of the mobile nodes. Consequently, the mobile node can perform fast authentication procedure with the new access network without a help of the local AAA server of the new access network. With the proposed scheme, low latency authentication operations can be achieved.
