This document describes how to further extend the Public Key
Cryptography for Initial Authentication in Kerberos (PKINIT)
extension (defined in RFC 4556) to exchange an opaque data blob that
a Key Distribution Center (KDC) can validate to ensure that the
client is currently in possession of the private key during a PKINIT
Authentication Service (AS) exchange.
This document is a product of the Common Authentication Technology Next Generation Working Group of the IETF.
This is now a Proposed Standard.
