Title : How to create dynamic UPNs for invited ATTENDEEs
Author(s) : D. Royer
Filename : draft-royer-calsch-dynamic-upn-00.txt
Pages : 1

This is an extension to the [CAP] and [iMIP] protocols. A CU may wish
to invite a UPN to an event where the UPN does not have a account on
the CU's CS or the S/MIME key to send encrypted [iMIP] messages. This
memo describes two methods to dynamically create UPNs in order for
those UPNs to gain access to the 'Organizers' CS and to add
authentication to [iMIP].
This memo also includes a description of how to include an [OTP]
challenge in an object directed to a CUA. The CUA must compute the
password in order to respond to the object. This challenge and its
response can be sent in the clear as the values are computed using a
secret that would not be known to anyone snooping the line. This adds
a level of security to iMIP communications.

In the body type:
"FILE /internet-drafts/draft-royer-calsch-dynamic-upn-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
Internet-Draft.
