Abstract

A network (20) comprises an authenticator node (22) and a server (24) such as an authentication, authorization, and accounting (AAA) server. A method comprises a terminal (30) sending authentication capabilities information (AC) across a network access interface (32) to the network (the authentication capabilities information provides an indication of authentication capabilities of the terminal). The network (20) then uses the authentication capabilities information to determine a first cryptographic value. The terminal (30) then uses the authentication capabilities information to determine a second cryptographic value. The network (20) compares the first cryptographic value and the second cryptographic value to authenticate the terminal.
