Local key exchange for mobile IPv6 local binding security association

This paper describes a key management protocol for a mobile computer to securely obtain keying material with an access router in a visited network for use as the local binding security association with the router. The protocol enables an IPv6 node to utilize an access router as its temporary home agent and continue to receive packets destined to its care-of address with the temporary home agent as well as to send packets from this care-of address when the nodes change its access router. To support this operation, a few new mobility headers and neighbor discovery options are defined.
