Title: CMS Symmetric Key Management and Distribution
State: Pending

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).
