Abstract
This presentation describes one of current security activities in IETF targeted to support Mobile IP architecture. It includes combined mutual
authentication and session key generation protocols for Mobile Nodes (MN)suitable for use at layer-2 in 802.1x networks (such as 802.11 wireless
LANs). The protocols apply to scenarios where a Mobile Node (MN) is in a foreign network such as public 802.3 network that uses Home-AAA and
Foreign-AAA services. The protocols assume a pre-deployed
cryptographically secure pre-shared key present on the MN, and use the 802.1X standard,Extensible Authentication Protocol (EAP) messages, and RADIUS
Authentication Servers. The protocols can easily be extended to support the migration
from RADIUS to DIAMETER. The protocols can also support wireless transport
layers other than 802.1x, such as CDMA-based Cdma2000 or UMTS.
