Abstract
A method of authenticating a user terminal with an access node providing restricted access to a communication network is provided. The method comprises the user terminal transmitting a request for an authentication token to a trusted network node via an unrestricted channel on the access node, the request comprising a network identity for a user of the user terminal. The network node verifies the identity of the user using the network identity, generates an authentication token and transmits the authentication token to the user terminal via the unrestricted channel. The user terminal derives login information from the authentication token and provides the login information to the access node. The access node authenticates the login information and removes the restricted access such that the communication network can be accessed by the user terminal.
