Abstract

   The Real-Time Communications on the Web (RTCWEB) working group is
   tasked with standardizing protocols for enabling real-time
   communications within user-agents using web technologies (e.g
   JavaScript).  The major use cases for RTCWEB technology are real-time
   audio and/or video calls, Web conferencing, and direct data transfer.
   Unlike most conventional real-time systems (e.g., SIP-based soft
   phones) RTCWEB communications are directly controlled by some Web
   server, which poses new security challenges.  For instance, a Web
   browser might expose a JavaScript API which allows a server to place
   a video call.  Unrestricted access to such an API would allow any
   site which a user visited to "bug" a user's computer, capturing any
   activity which passed in front of their camera.  [I-D.ietf-rtcweb-
   security] defines the RTCWEB threat model.  This document defines an
   architecture which provides security within that threat model.
