<p>On initial connection between a terminal 21 and an authentication server 29 by way of an intermediate access hub 23, a session key Ks is generated (67), and transmitted to the hub from the server. When a communications connection is to be established between the terminal and the access hub, requiring further authentication, the terminal transmits the session key to the hub (70), to be compared with the counterpart previously stored in the hub. This arrangement allows the hub to be configured on request from the terminal without further reference to the server</p> |
