          Privacy Enhanced RTP Conferencing
          IETF 99
          Session 2017-07-18 9:30 - 12:00
          Chairs :- Suhas Nandakumar, Nils Ohlmeier
          Scribe: Roni Even
          Jabber: Matt Miller
          * draft-ietf-perc-double, draft-ietf-perc-srtp-ekt-diet
            - Cullen presented a new way to do OHB (now in payload), a joint
              from Sergio and Cullen
            - Presentation also focussed on doing RTP Repair (RTX, RED, Flexfec)
            in PERC
               —- Idea is to do repair on the double encrypted packet
            - Ekt draft had no technical changes and may need some changes due to
            the new
              OHB proposal
            - Chairs made the consensus call and there was strong consensus
              on the overall direction of the new OHB proposal as well as the repair
              procedures in PERC
            - Authors to submit new version detailing the proposals.
          * draft-ietf-perc-private-media-framework
            - Paul presented on the editorial changes related to PERC key-management
            & packet
            - No major open issues.
            - Expected reviews
          * draft-ietf-perc-dtls-tunnel
            - Paul presented on the changes related to removal of dlts-id and
              of the tls-id in the tunnel, make association ID as UUID and other
              editorial changes for better readability.
            - No major open issues.
            - Expected reviews
          * Action Items and Next Steps
            - Chairs to confirm the consensus on the list
            - Double Authors to submit updated version.
            - Chairs to setup virtual interim to help progress the decisions
              made in this meeting.
          Raw Notes (Roni Even)
          Chairs Intro
          New Chair – Nils
          No comments on milestones
           SRTP Double draft-ietf-perc-double  - Cullen
          EKT on Diet draft-ietf-perc-srtp-ekt-diet – Cullen
          What is lite – SRTP in SRTP
          FlexFEC – usually before encryption
          In PERC – before, after or in the middle.
          A option after double
          B option before – MD cannot do repair
          Lite – after E2E before HBH
          RED – Magnus asked about RED what happenes with payload type when
          changing from non red to red in the MD. Need detailed information about
          how it will work.
          Proposal – move obh to payload after header.  – slide 15
          Roni – how will the SDP work,
          Cullen – no change still original payload since encrypted.
          Mo : how does framemarking works. Marker bit is not enough.
          Cullen : do we allow SFU to set the m-bit.
          Consensus: the M bit can be changed by SFU
          Cullen: the bitfield work, maybe from the MD to KD to client.
          The proposal: Move OHB information from header extension to payload,
          use RTX,RED and flexfec as in “A”. DTMF: MD cannot receive DTMF. (Add
          text as Magnus requested).
          Consensus on slide 16 : the WG accepted the direction. Expect verification
          of the solution for next meeting.
          EKT issue (18) – add in to the DTLS EKT messge , the value of bitfiled
          value for the new Double payload if we make the OHB->payload change.
          Cullen : can be by defining multiple protection profiles instead of
          change as above.
          Action: Need to verify using multiple profiles for different bitmaps
           DTLS Tunnel draft-ietf-perc-dtls-tunnel – Paul Jones
          TLS-ID – remove the editor note – will be out of scope
          PERC Framework draft-ietf-perc-private-media-framework – Paul Jones
          Added two appendixes – appendix B will need an update based on the
          payload structure change.
