Abstract
This document describes a general Data Validation and Certification
Server (DVCS) 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.
Useful Data Validation and Certification Server responsibilities in a
PKI are to assert the validity of signed documents, public key
certificates, and the possession or existence of data.
Assertions created by this protocol are called Data Validation
Certificates (DVC).
We give examples of how to use the Data Validation and Certification
Server to extend the lifetime of a signature beyond key expiry or
revocation and to query the Data Validation and Certification Server
regarding the status of a public key certificate. The document
includes a complete example of a time stamping transaction.
