Technical Summary

  There are many scenarios in which users must be able to prove the
  existence of data at a specific point in time and be able to
  demonstrate the integrity of data since that time, even when the
  duration from time of existence to time of demonstration spans a large
  period of time.  Additionally, users must be able to verify signatures
  on digitally signed data many years after the generation of the
  signature.  This document describes a class of long-term archive
  services to support such scenarios and the technical requirements for
  interacting with such services.

Working Group Summary
