The posted new draft addresses two comments from the IESG:
- The first one was that the references needed to be broken out to indicate which documents are informative and which are normative.
- The second was a concern about reply attacks. We added the CMS signingTime attribute to ever signed message.
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-08.txt Pages : 81 Date : 2002-12-16 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  and Certificate Management Message over CMS (CMC) protocol  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).

After logging in, type "cd internet-drafts" and then "get draft-ietf-smime-symkeydist-08.txt". A list of Internet-Drafts directories can be found in http://www.ietf.org/shadow.html or ftp://ftp.ietf.org/ietf/1shadow-sites.txt Internet-Drafts can also be obtained by e-mail. Send a message to: mailserv(_at_)ietf(_dot_)org. In the body type: "FILE /internet-drafts/draft-ietf-smime-symkeydist-08.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.
