  1. BANAID: A Sensor Network Test-Bed for Wormhole Attack HaniAlzaid Suhail Abanmi Salil Kanhere Chun Tung Chou BANAID

  2. Overview • Background. • The Wormhole Attack on WSN. • BANAID. • Conclusion.

  3. Sensor Networks • Distributed network of wireless nodes that monitor the environment or other systems. • Deployed in large numbers • Nodes have limited battery life • Nodes have low computational power • Nodes have small data storage Background

  4. Sensor Networks Base station A s1 s0 Thousands of small devices with sensors communicating wirelessly Background

  5. WSN Application • Civil structural monitoring • Habitat/ecosystem monitoring • Environmental monitoring • Smart homes • Chemical Detection • Traffic/Vehicle Monitoring • Human Health Monitoring • Homeland Security Background

  6. QUIZ • What are the limited resources in WSN? • Energy, memory, and computation. • Energy, communication, and memory. • Computation, communication, and memory. Background

  7. QUIZ WINNER IS… • Who is it?

  8. Overview • Background. • The Wormhole Attack on WSN. • BANAID. • Conclusion.

  9. Routing Tree Adapted from Chris Karlof and David Wagner's WSNPA slides Wormhole Attack

  10. Routing Adapted from Chris Karlof and David Wagner's WSNPA slides Wormhole Attack

  11. Wormhole Attack • Tunnel packets received in one place of the network and replay them in another place • The attacker can have no key material. All it requires is two transceivers and one high quality out-of-band channel Adapted from Chris Karlof and David Wagner's WSNPA slides Wormhole Attack

  12. Disrupted Routing • Most packets will be routed to the wormhole • The wormhole can drop packets or more subtly, selectively forward packets to avoid detection Adapted from Chris Karlof and David Wagner's WSNPA slides Wormhole Attack

  13. Overview • Background. • The Wormhole Attack on WSN. • BANAID. • Conclusion.

  14. BANAID • BANAID is composed of: • 7 Mica2 sensors. • 2 Stargates. • The topology is assumed to be fixed. • Each sensor knows its neighbors. BANAID

  15. BANAID • Three programs have been written and installed: • TOSBase program (sensor 5, and 6). • Stargate program (stargate 1, and 2). • Simple customized AODV program (sensor 1,2,3 and 4). BANAID

  16. BANAID • Timing mechanism is required to detect Wormhole attack[1]. • The average transmission delay in each sensor is ≈45 msec (Td ≈ 45msec) [2]. BANAID

  17. BANAID • Delay on the real path: Ns * Td. 3 * Td. • Delay on the fake path: Ns * Td. 2 * Td BANAID

  18. Overview • Background. • The Wormhole Attack on WSN. • BANAID. • Conclusion.

  19. Conclusion • Wormhole attack is a significant danger to routing protocols WSN. • BANAID implemented one of the Wormhole attack’s solutions for WSN which is Packet Leaches [1]. • The destination is able to detect the fake packet if the difference in time stamp is < (Ns * Td) where Ns is the number of sensors/hops between source and destination in the real path.

  20. QUIZ • What is the function of TOSBase? • Initiates Wi-Fi connection • Exchange packets with other Mica2 • Forwards packets received from radio antenna to serial port and vice versa. • Exchange routing information.

  21. QUIZ WINNER IS… • Who is it?
