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
pathname: RFC:RFC989.TXT
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.
Public access files may be copied from the <RFC> directory at
SRI-NIC.ARPA via FTP with username ANONYMOUS and password GUEST.
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.
