See full text

A method of preauthenticating a mobile node in advance of a switch from a current point of attachment (CPoA) to a next point of attachment (NPoA) is disclosed. One or more preauthentication requests are received at the CPoA. The one or more preauthentication requests include a proxy assignment from the mobile node. Each of the one or more preauthentication requests corresponds to one of one or more possible points of attachment (PPoAs). Using the CPoA, the mobile node is preauthenticated with the one or more PPoAs using a transitivity of trust between the mobile node, the CPoA, and one or more authentication servers.
