This document describes a mechanism to manage (i.e., set up,
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 mechanism uses the
Cryptographic Message Syntax (CMS) protocol and Certificate
Management 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
Secure/Multipurpose Internet Mail Extensions (S/MIME) Mail List Agents
(MLAs). [STANDARDS TRACK]
This document is a product of the S/MIME Mail Security Working Group of the IETF.
This is now a Proposed Standard Protocol.
STANDARDS TRACK: This document specifies an Internet standards track
protocol for the Internet community,and requests discussion and suggestions
for improvements. Please refer to the current edition of the Internet
Official Protocol Standards (STD 1) for the standardization state and
