Abstract:
   This document describes unknown key-share attacks on the use of
   Datagram Transport Layer Security for the Secure Real-Time Transport
   Protocol (DTLS-SRTP).  Similar attacks are described on the use of
   DTLS-SRTP with the identity bindings used in Web Real-Time
   Communications (WebRTC) and SIP identity.  These attacks are
   difficult to mount, but they cause a victim to be mislead about the
   identity of a communicating peer.  Mitigation techniques are defined
   that implementations of RFC 8122 are encouraged to deploy.
