Technical Summary: Opportunistic Secure Real-time Transport Protocol (OSRTP) is an implementation of the Opportunistic Security mechanism, as defined in RFC 7435, applied to Real-time Transport Protocol (RTP). OSRTP allows encrypted media to be used in environments where support for encryption is not known in advance, and not required. OSRTP does not require 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 SRTP. OSRTP is a transitional approach useful for migrating existing deployments of real-time communications to a fully encrypted and authenticated state. Working Group Summary: There is consensus in the WG around this document. Document Quality: Section 6 of the document (to be removed before its publication as an RFC) discusses the implementation status of the techniques described in the document. Personnel: Gonzalo Camarillo is the Document Shepherd. Alexey Melnikov Campbell is the responsible AD.
