A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the S/MIME Mail Security Working Group of the IETF.
Title : CMS Symmetric Key Management and Distribution
Author(s) : S. Turner
Filename : draft-ietf-smime-symkeydist-09.txt
Pages : 81
Date : 2003-1-14
This document describes a mechanism to manage (i.e., setup,
distribute, and rekey) keys used with symmetric cryptographic
algorithms. Also defined herein is a mechanism to organize users
into groups to support distribution of encrypted content using
symmetric cryptographic algorithms. The mechanisms use the
Cryptographic Message Syntax (CMS) protocol [2] and Certificate
Management Message over CMS (CMC) protocol [3] to manage the
symmetric keys. Any member of the group can then later use this
distributed shared key to decrypt other CMS encrypted objects with
the symmetric key. This mechanism has been developed to support
S/MIME Mail List Agents (MLAs).

In the body type:
"FILE /internet-drafts/draft-ietf-smime-symkeydist-09.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.
