EAP is an authentication protocol which supports multiple authentication
mechanisms. EAP typically runs directly over the link layer without
requiring IP and therefore includes its own support for in-order
delivery and re-transmission. While EAP was originally developed for use
with PPP, it is also now in use with IEEE 802. This document defines the
One Time Password (OTP) and Generic Token Card EAP methods, both of
which provide one-way authentication, but not key generation. As a
result, the OTP and Generic Token Card methods, when used by themselves,
are only appropriate for use on networks where physical security can be
assumed. These methods SHOULD NOT be used on wireless networks, or over
the Internet, unless the EAP conversation is protected. This can be
accomplished using technologies such as IPsec or TLS.

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
