Abstract

   This document updates PKINIT, as defined in RFC 4556, to remove
   protocol structures tied to specific cryptographic algorithms.  The
   PKINIT key derivation function is made negotiable, the digest
   algorithms for signing the pre-authentication data and the client's
   X.509 certificates are made discoverable.

   These changes provide preemptive protection against vulnerabilities
   discovered in the future against any specific cryptographic
   algorithm, and allow incremental deployment of newer algorithms.

Status of This Memo

   This Internet-Draft is submitted in full conformance with the
   provisions of BCP 78 and BCP 79.

   Internet-Drafts are working documents of the Internet Engineering
   Task Force (IETF).  Note that other groups may also distribute
   working documents as Internet-Drafts.  The list of current Internet-
   Drafts is at http://datatracker.ietf.org/drafts/current/.

   Internet-Drafts are draft documents valid for a maximum of six months
   and may be updated, replaced, or obsoleted by other documents at any
   time.  It is inappropriate to use Internet-Drafts as reference
   material or to cite them other than as "work in progress."

   This Internet-Draft will expire on October 1, 2017.
