Abstract
In a method for authenticating a device on a wireless local area network (WLAN) there is a once-off registration phase in which the device sends registration data in a MO SMS via the mobile network to the authentication system, and the authentication system performs a query to this mobile network to validate the subscriber and resolve the subscriber and device identifiers. The device receives network access information from the authentication system, allowing it to generate network access credentials on an on-going basis. This is permanent unless the registration is revoked due, for example, to the device being stolen. The network access information may be provided by the authentication system generating and signing a unique subscriber certificate during registration, and the device downloading it. The device uses the signed certificate to generate and encrypt the network access credentials for the network access.
