First Claim
Patent Images
1. A method for authenticating a roaming device with a network, comprising the steps of:
- generating, by an authentication server of the network, authentication data associated with the roaming device;
sending the authentication data to access points of the network, the access points being connected to the authentication server; and
when the roaming device roams to a particular access point of the access points, using the authentication data to locally authenticate the roaming device at the particular access point.

Abstract
A method and system for authenticating a roaming device with a network is described. The roaming device initially is authenticated with an authentication server that sends authentication information to remote access points. When the roaming device enters in contact with one of the access points, a local authentication is performed between the access point and the roaming device to allow the device to access the network.

10. A method for authenticating a roaming device with a network, comprising the steps of:
-
connecting the roaming device with an authentication server upon a contact of the roaming device with a first access point of the network;
authenticating the roaming device with the authentication server;
generating authentication data for the roaming device;
distributing the authentication data to the first access point and a second access point of the network; and
locally authenticating the roaming device upon a contact with the second access point using the distributed authentication data. - View Dependent Claims (11, 12, 13, 14, 15)

16. A system for authenticating a roaming device with a network, comprising:
-
an authentication server connected to the network; and
first and second access points connected to the authentication server, the first and second access points being capable of communicating with the roaming device, each of the first and second access points including a memory arrangement capable of storing authentication data corresponding to the roaming device, wherein the authentication server sends the authentication data to the first and second access points upon an initial authentication procedure of the roaming device with the first access point, and wherein the second access point locally authenticates the roaming device upon a contact of the roaming device with the second access point. - View Dependent Claims (17, 18)

19. A method for authenticating a roaming device with a network, comprising the steps of:
-
with an authentication server, receiving an authentication request from a roaming device, the request being encrypted with a first shared code;
with the authentication server, generating a session key associated with the roaming device;
sending the session key to an access point of the network, the session key being encrypted with a second shared code; and
utilizing the session key to authenticate the roaming device at the access point, and to encrypt data exchanged between the roaming device and the access point. - View Dependent Claims (20, 21)
