draft-ietf-sip-media-security-requirements-03

Comment: “re-instate R15”

  • R15: start with RTP and upgrade to SRTP

    • For announcements, advertising

  • Concern:

    • Attacker could send bogus RTP media until SRTP starts (assuming SRTP starts at all)‏

    • Brian Stucker analyzed a similar RTP problem

  • Further study? Re-instate requirement?
