In a public wireless Local Area Network (WLAN) access service using
Mobile IP, network elements, such as access points, access routers,
home agents and mobility anchor points, are required to authenticate
the user to prevent unauthorized usage. Therefore, a mobile node
needs to execute the authentication process many times to use the
Mobile IP function. It will increase the connection delay. The
connection delay can be reduced by using a preshared key as an
authentication method. But it is necessary to share the symmetric
secret key between network element (NE) and mobile node (MN) in
advance. It is impossible for the MN to configure the key of all
network elements in advance.
In this document we discuss a secure access architecture using an
Extensible Authentication Protocol (EAP) key as a shared key between
NEs and an MN.

NOTE:	The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.
