¿µ¹® ³»¿ë¿ä¾à This standard describes a mechanism of transporting a fingerprint attribute in the Session Description Protocol(SDP) that identifies the key that will be presented during the DTLS handshake. The key exchange travels along the media path as opposed to the signaling path. The SIP Identity mechanism can be used to protect the integrity of the fingerprint attribute from modification by intermediate proxies.
