Opportunistic Secure Real-time Transport Protocol (OSRTP) is an
implementation of the Opportunistic Security mechanism, as defined in
RFC 7435, applied to the Real-time Transport Protocol (RTP). OSRTP
allows encrypted media to be used in environments where support for
encryption is not known in advance and is not required. OSRTP does
not require Session Description Protocol (SDP) extensions or features
and is fully backwards compatible with existing implementations using
encrypted and authenticated media and implementations that do not
encrypt or authenticate media packets. OSRTP is not specific to any
key management technique for Secure RTP (SRTP). OSRTP is a
transitional approach useful for migrating existing deployments of
real-time communications to a fully encrypted and authenticated
state.
