Title : EAP Tunneled TLS Authentication Protocol (EAP-TTLS)

EAP-TTLS is an EAP protocol that extends EAP-TLS. In EAP-TLS, a TLS
handshake is used to mutually authenticate a client and server. EAP-
TTLS extends this authentication negotiation by using the secure
connection established by the TLS handshake to exchange additional
information between client and server. In EAP-TTLS, the TLS
handshake may be mutual; or it may be one-way, in which only the
server is authenticated to the client. The secure connection
established by the handshake may then be used to allow the server to
authenticate the client using existing, widely-deployed
authentication infrastructures such as RADIUS. The authentication of
the client may itself be EAP, or it may be another authentication
protocol such as PAP, CHAP, MS-CHAP or MS-CHAP-V2.
Thus, EAP-TTLS allows legacy password-based authentication protocols
to be used against existing authentication databases, while
protecting the security of these legacy protocols against
eavesdropping, man-in-the-middle and other cryptographic attacks.
EAP-TTLS also allows client and server to establish keying material
for use in the data connection between the client and access point.
The keying material is established implicitly between client and
server based on the TLS handshake.

In the body type:
"FILE /internet-drafts/draft-ietf-pppext-eap-ttls-02.txt".
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.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
