Abstract
In order to delegate location update signaling responsibility from a Mobile Node to a Mobile Router, the Mobile Router is provided with a second symmetric key generated by a Mobile Node using a first symmetric key shared between the Mobile Node and a Peer Node. The Mobile Router is additionally provided with a 'certificate' authenticating the second symmetric key using the first symmetric key. In this way, the mobile router can sign location update related messages sent to the Peer Node with the second symmetric key, and can provide the Peer Node with the certificate in order to allow the Peer Node to authenticate the right of the Mobile Router to act on behalf of the Mobile Node.
