Abstract

The S/MIME [RFC5751] standard defines a data encapsulation format for the achievement of end-to-end security services such as integrity, authentication, non-repudiation, and confidentiality. By default, S/MIME secures message body parts, at the exclusion of the message header fields.

                    Securing Header Fields with S/MIME

Abstract

   This document describes how the S/MIME protocol can be extended in    order to secure message header fields defined in RFC 5322.  This    technology provides security services such as data integrity, non-    repudiation, and confidentiality.  This extension is referred to as    'Secure Headers'.
