Title : Internet X.509 Public Key Infrastructure Data

This document describes a general data validation and certification
service and the protocols to be used when communicating with it. The
Data Validation and Certification Server is a Trusted Third Party
(TTP) that can be used as one component in building reliable non-
repudiation services (see [ISONR]).
Useful Data Validation and Certification Server responsibilities in a
PKI are to validate signed documents and to assert the validity of
public key certificates at a given time.
We give examples of how to use the Data Certification Server to
extend the lifetime of a signature beyond key expiry or revocation
and to query the Data Certification Server regarding the status of a
public key certificate.
<draft>Note: The initial drafts of this protocol used the
abbreviation DCS instead of DVCS.</draft>

NOTE: The mail server at ietf.org 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.
