  1. Project OrdaSecure Key Distribution Over Ad Hoc Networks Security in Ad Hoc Networks – Team A Lane Westlund, Roderic Campbell, Mark Allen, Dima Novikov, David Campbell

  2. Agenda • Review of Iolus, Key Graph Theories • Goals & Non-Goals • Schedule Review • Current Status • System Overview • Testing & Performance • Demonstration

  3. Review of Iolus, Key Graph Theories • Goal of the Papers: Scalable, secure strategy for securely distributing re-key messages • As previously explained, Group-Oriented Re-keying: • Takes advantage of multicasting to send re-key messages • Needs small number of messages on join/leave • Outperforms User- and Key-Oriented Re-key

  4. Review of Iolus, Key Graph Theories (Cont’d) • Problems with paper: • Makes assumptions about server’s capabilities • Ignores common problems (mass drop-off, etc.) • Doesn’t map well to ad hoc setting

  5. Goals & Non-Goals • Goals • Secure Key Distribution • Scalable Key Distribution • No Static Central Authority/Server • Dynamic Topology • Mass Drop-Off Tolerant • Unique Keys for Each Server

  6. Goals & Non-Goals • Non-Goals • User authentication • Access control • Malicious initial user • Preventing attacks by trusted members • Simultaneous joins

  7. System Overview • Implemented our own rekeying algorithm, which uses ideas from the Iolus and Key Graph papers. • Minimizes necessary messages for secure key distribution • Algorithm example...

  8. Week 5: Implementation Class testing Limited integration Code review Week 6: Implementation Unit testing (contractual) Unit integration Code review Week 7: Full integration Stress testing Documentation finalization Week 8: Submit project Schedule

  9. Current Status • Not Mass-Join Tolerant • Synchronization Issues • Demo Application Works with Orda

  10. Testing & Performance • Constant-time (roughly 12 seconds on CS machines) system updating after a user has left • Could not test scalability effectively

  11. Demonstration & Questions • Code, javadoc, paper on website: http://www.cs.rit.edu/~p590-01a/
