A new Request for Comments is now available in online RFC libraries. RFC 3029 Title: Internet X.509 Public Key Infrastructure Data Validation and Certification Server Protocols Author(s): C. Adams, P. Sylvester, M. Zolotarev, R. Zuccherato Status: Experimental Date: February 2001 Mailbox: cadams@entrust.com, mzolotarev@baltimore.com, peter.sylvester@edelweb.fr, robert.zuccherato@entrust.com Pages: 51 Characters: 107347 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-pkix-dcs-07.txt URL: ftp://ftp.rfc-editor.org/in-notes/rfc3029.txt 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. This document is a product of the Public-Key Infrastructure (X.509) Working Group of the IETF.
