Draft S/MIME - CMS Symmetric Key Management and Distribution

29.01.2008
Abstract :

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 mechanism uses the Cryptographic Message Syntax (CMS) protocol [CMS] and Certificate Management Message over CMS (CMC) protocol [CMC] 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.
