New ID of possible interest

I would like to inform the SMIME working group of a newly-submitted
Internet Draft that may be of interest:

 The With-MAC key-wrapping algorithm for Cryptographic Message Syntax

  draft-herzog-withmac-keywrap-00

Abstract:

   This document describes a new key-wrapping algorithm to be used in
   the EnvelopedData, AuthenticatedData and AuthEnvelopedData structures
   of the Cryptographic Message Syntax.  Because these structures do not
   provide data-origin authentication, a recipient cannot
   cryptographically verify that the plaintext received was the
   plaintext encapsulated by the message's original sender.  The With-
   MAC key-wrapping algorithm allows an EncryptedKey value to hold both
   a wrapped symmetric key and a MAC value on the data to be
   authenticated.  When used in EnvelopedData, AuthenticatedData and
   AuthEnvelopedData structures, therefore, these structures can achieve
   data-origin authentication (in some circumstances) using only
   symmetric-key algorithms.

https://datatracker.ietf.org/doc/draft-herzog-withmac-keywrap/

A side note: this draft should probably be read in combination with our previous draft on static-static
ECDH (https://datatracker.ietf.org/doc/draft-herzog-static-ecdh/). That draft described how a
sender might use a certified ECDH key to create an EnvelopedData structure (for example). It is unclear,
however, how such a sender could also provide data-origin authentication without using digital
signatures. However, that requires a certified signature-capable key, something they may not have.
This draft provides an alternate approach-- the sender provides a MAC value for each recipient.

FYI

-------- Original Message --------
Subject: Document Action: 'Suite B in Secure/Multipurpose Internet Mail 
Extensions (S/MIME)' to Informational RFC	(draft-housley-rfc5008bis-01.txt)
Date: Tue, 26 Apr 2011 11:48:57 -0700
From: The IESG <iesg-secretary <at> ietf.org>
To: IETF-Announce <ietf-announce <at> ietf.org>
CC: RFC Editor <rfc-editor <at> rfc-editor.org>

The IESG has approved the following document:
- 'Suite B in Secure/Multipurpose Internet Mail Extensions (S/MIME)'
   (draft-housley-rfc5008bis-01.txt) as an Informational RFC

This document has been reviewed in the IETF but is not the product of an
IETF Working Group.

The IESG contact person is Sean Turner.

A URL of this Internet Draft is:
http://datatracker.ietf.org/doc/draft-housley-rfc5008bis/

Technical Summary

   The United States Government has published guidelines for
   "NSA Suite B Cryptography", which defines cryptographic
   algorithm policy for national security applications. This
   document defines a profile of S/MIME which is conformant with
   Suite B.
