1.  Introduction

   [I-D.ietf-acme-acme] is a mechanism for automating certificate
   management on the Internet.  It enables administrative entities to
   prove effective control over resources like domain names, and
   automates the process of generating and issuing certificates.
   [I-D.ietf-acme-authority-token] extends ACME to provide a general
   method of extending the authority and authorization of entities to
   control a resource via a third party Token Authority beyond the
   Certification Authority.

   This document addresses the STIR problem statement [RFC7340] which
   identifies the need for Internet credentials that can attest
   authority for the originator of VoIP calls in order to detect
   impersonation, which is currently an enabler for common attacks
   associated with illegal robocalling, voicemail hacking, and swatting.
