<p>A key distribution method for the next generation network (NGN), includes: (a) a terminal sending a registration request message to a softswitch; (b) the softswitch sending a authentication request message to a authentication center; (c) the authentication center authenticating the terminal, then the softswitch distributing the session key to the terminal after the registration authentication being passed. The invention implements the key distribution during the registration authentication, thus the traffic is less, and it could combine the specialty of the NGN, and improve the efficiency for solving the security problem, the registration authentication of the terminal and the distribution of the key are more fit for the NGN actually.</p> |
