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 : Enhanced Security Services for S/MIME
Author(s) : P. Hoffman
Filename : draft-ietf-smime-ess-02.txt
Pages : 35
Date : 16-Feb-98
This document describes three optional security service extensions for
S/MIME. These services provide functionality that is similar to the Message
Security Protocol [MSP], but are useful in many other environments,
particularly business and finance. The services are:
- signed receipts
- security labels
- secure mailing lists
The services described here are extensions to S/MIME version 2 [SMIME2] and
S/MIME version 3 [SMIME3]. Most of this document can be used with S/MIME
version 2, which relies on PKCS #7 version 1.5 [PKCS7-1.5]. A small number
of the services require mechanisms described in Cryptographic Message
Syntax [CMS]. The format of the messages are described in ASN.1:1988
[ASN1-1988] with the modification that BMPString and UniversalString
types from ASN.1:1994 [ASN1-1994] are used in the descriptions.

Send a message to: mailserv(_at_)ds(_dot_)internic(_dot_)net(_dot_) In
the body type:
"FILE /internet-drafts/draft-ietf-smime-ess-02.txt".
NOTE: The mail server at ds.internic.net 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.
