Internet Engineering Task Force (IETF) M. Thomson Request for Comments: 8292 Mozilla Category: Standards Track P. Beverloo ISSN: 2070-1721 Google November 2017 Voluntary Application Server Identification (VAPID) for Web Push Abstract An application server can use the Voluntary Application Server Identification (VAPID) method described in this document to voluntarily identify itself to a push service. The "vapid" authentication scheme allows a client to include its identity in a signed token with requests that it makes. The signature can be used by the push service to attribute requests that are made by the same application server to a single entity. The identification information can allow the operator of a push service to contact the operator of the application server. The signature can be used to restrict the use of a push message subscription to a single application server. Status of This Memo This is an Internet Standards Track document.

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 unwanted constraint on the interactions between user agents andShow full document text
