              CDNI interfaces update for HTTPS delegation
            draft-fieau-cdni-interfaces-https-delegation-01

Abstract

   The delivery of content over HTTPS involving multiple CDNs raises
   credential management issues.  This document recalls the methods
   under study at the IETF.  Then it specifies the updates needed in
   CDNI Control and Metadata interfaces to setup HTTPS delegation
   between an uCDN and dCDN.

1.  Introduction

   When content is delivered over HTTPS using one or more CDNs along the
   path, credential management is required.  This is specifically
   required when an entity delegates delivery of encrypted content to
   another trusted entity.  This document presents updates needed in
   CDNI Control and Metadata interfaces to setup HTTPS delegation
   between an uCDN and dCDN.

   Several delegation methods are currently proposed within several IETF
   working groups (refer to [I-D.fieau-cdni-https-delegation] for an
   overview of delegation works ongoing at the IETF).  They specify
   separately the provisioning of their credentials.

   This document specifies an update to the CDNI control / Triggers and
   Metadata interfaces to support these methods.  Furthermore, it
   includes a proposal of registry to enable the adding of new methods
   in the future.

   Section 2 is about terminology used in this document.  Section 3
   presents delegation methods specified at the IETF.  Section 4
   introduces a secured delegation object for CDNI.  Section 5 addresses
