RFC 989:
 
   Title:       Privacy Enhancement for Internet Electronics Mail:
                Part I:  Message Encipherment and Authentication
                Procedures
   Author:      John Linn
   Mailbox:     [log in to unmask]
   Pages:       23
   Characters:  63934

   This RFC suggests a proposed protocol for the Internet community and
   requests discussion and suggestions for improvements.  This RFC is
   the outgrowth of a series of IAB Privacy Task Force meetings and of
   internal working papers distributed for those meetings.  This RFC
   defines message encipherment and authentication procedures, as the
   initial phase of an effort to provide privacy enhancement services
   for electronic mail transfer in the Internet. It is intended that the
   procedures defined here be compatible with a wide range of key
   management approaches, including both conventional (symmetric) and
   public-key (asymmetric) approaches for encryption of data encrypting
   keys.  Use of conventional cryptography for message text encryption
   and/or authentication is anticipated.
 
   Privacy  enhancement services (confidentiality, authentication, and
   message integrity assurance) are offered through the use of end-to-
   end cryptography between originator and recipient User Agent
   processes, with no special processing requirements imposed on the
   Message Transfer System at endpoints or at intermediate relay sites.
   This approach allows privacy enhancement facilities to be
   incorporated on a site-by-site or user-by-user basis without impact
   on other Internet entities.  Interoperability among heterogeneous
   components and mail transport facilities is supported.  Distribution
   of this memo is unlimited.

   The normal method for distribution of RFCs is for interested parties
   to copy the documents from the NIC online library using FTP.
   Requests for special distribution should be addressed to either the
   author of the RFC in question or to [log in to unmask]  Unless
   specifically noted otherwise on the RFC itself, all RFCs are for
   unlimited distribution.
