    Voluntary Application Server Identification (VAPID) for Web Push
                      draft-ietf-webpush-vapid-03

Abstract

   An application server can use the method described to voluntarily
   identify itself to a push service.  This identification information
   can be used by the push service to attribute requests that are made
   by the same application server to a single entity.  An application
   server can include additional information that the operator of a push
   service can use to contact the operator of the application server.
   This identification information can be used to restrict the use of a
   push subscription a single application server.

1.  Introduction

   The Web Push protocol [RFC8030] describes how an application server
   is able to request that a push service deliver a push message to a
   user agent.

   As a consequence of the expected deployment architecture, there is no
   basis for an application server to be known to a push service prior
   to requesting delivery of a push message.  Requiring that the push
   service be able to authenticate application servers places an
