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.
