  1. Secure IGMP/MLD IETF84-PIM J. William Atwood Bing Li Concordia University, Montreal

  2. Problem Statement How to ensure that an IGMP/MLD “expression of interest” in joining a group comes from a legitimate member of the group? Assumption: The End User host and the Designated Router (DR) each hold a copy of a key given to them by a third party. IETF 84-PIM

  3. Architecture Authority Key Key Designated Router End User host IETF 84-PIM

  4. LAN environment Querier Designated Router Non-Querier End User host End User host IETF 84-PIM

  5. Operation We believe that there are three roles on the router side: Querier, Non-Querier, and Designated Router Initially, the DR and the End User hold the allocated key The second End User MAY share a different key with the DR All three router roles and all hosts that are members of the group must be able to hear each other securely. IETF 84-PIM

  6. Questions • Is anyone aware of work of this type in the IETF? • Is there interest in formulating a (reasonably) general solution? • Based on the availability of a key shared between the DR and the EU(s). • william.atwood@concordia.ca IETF 84-PIM
