CDNI extensions for HTTPS delegation
draft-ietf-cdni-interfaces-https-delegation-04
Abstract
The delivery of content over HTTPS involving multiple CDNs raises
credential management issues. This document proposes extensions in
CDNI Control and Metadata interfaces to setup HTTPS delegation from
an Upstream CDN (uCDN) to a Downstream CDN (dCDN).

1. Introduction
Content delivery over HTTPS using one or more CDNs along the path
requires credential management. This specifically applies when an
entity delegates delivery of encrypted content to another trusted
entity.
Several delegation methods are currently proposed within different
IETF working groups. They specify different methods for provisioning
HTTPS delivery credentials.
This document extends the CDNI Metadata interface to setup HTTPS
delegation between an upstream CDN (uCDN) and downstream CDN (dCDN)
using the Standardized delegation methods. Furthermore, it includes
a proposal of IANA registry to enable adding of new methods.
Section 2 is about terminology used in this document. Section 3
presents delegation methods specified at the IETF. Section 4
addresses the extension for handling HTTPS delegation in CDNI.
Section 5 describes simple data types. Section 6 addresses IANA
registry for delegation methods. Section 7 covers the security
issues. Section 8 is about comments and questions.
