Title:
SECURE PROXY MOBILE IP APPARATUS, SYSTEM, AND METHOD
Document Type and Number:
WIPO Patent Application WO2007011995
Kind Code:
B1
Abstract:
A Proxy mobile node (PMN) in a visited access network securely issues mobile IP (MIP) registrations on behalf of a roaming mobile node, wherein the mobile node has no prior trust relationship with the visited access network. During access authentication (e.g. using EAP to authenticate to a home AAA server) , key material is derived (e.g. master session key sent by the home AAA to the authenticator in the visited network) . Further keys (PMN-AAA key) may be derived and sent to the PMN. The proxy uses the derived key to protect the MI registration and to bootstrap a PMN-HA key for- authenticating the MIP message between the PMN and the HA using a procedure according to RFC-3957.
