Title : The EAP MD5-Tunneled Authentication Protocol
(EAP-MD5-Tunneled)
Author(s) : P. Funk

EAP-MD5-Tunneled is an EAP protocol designed for use as an inner
authentication protocol within a tunneling EAP protocol such as EAP-
TTLS or EAP-PEAP. It is cryptographically equivalent to standard
CHAP and the EAP-MD5-Challenge protocol. It can be used inside an
EAP tunnel without exposing the system to the type of man-in-the-
middle attack which use of CHAP or the original MD5 Challenge
protocol is subject to, yet it is capable of being converted to CHAP
credentials at the tunneling endpoint for proxy forwarding to legacy
AAA servers, with no modification required of the legacy AAA server.
It may also be converted to EAP-MD5-Challenge credentials at the
tunneling endpoint for the purpose of proxy; however, the downstream
server that terminates the EAP-MD5-Challenge must be modified to
provide a challenge that meets certain criteria.

In the body type:
"FILE /internet-drafts/draft-funk-eap-md5-tunneled-00.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
