  1. Security Issues in Mobile Ad-Hoc Network Mukul A. Khairatkar

  2. Agenda • Introduction to MANET • Various Security Model • Operations • Introduction to IPSec • IPSec Operation • Simulation Details • Conclusion

  3. Mobile Ad-Hoc Network • No Infrastructure No Server  Nothing • Everybody acts like a Router • Security Problem • Network Resources • Source Spoofing • Eavesdropping • Data Transformation

  4. Security • Key Pre-Distribution Scheme • Web of Trust • Public Key Certification • IPSec

  5. Some Security Terms • Public Key • Private Key • Digital Signature • Certificate • Digital Signature • Certificate Of Authority • Certificates • Public Key Infrastructure • X.509

  6. Key Pre-distribution Scheme Node 2 Node 1 Key Key Key Key Key Node 3 Key Node 4

  7. Web Of Trust Public Key Node 1 Node 2 PGP PGP Public Key Node 3 PGP

  8. Public Key Infrastructure • X.509 • Certificate Authority CA • CA  CA Root Certificate • Root certificate • Distributed with Web Browser ..etc • SSL/TLS web pages

  9. IPSec • Why IPSec? • Open Standard Freely Available • Modular • Integrates in Existing IP structure • Transparent to application layer entities • For IPv6

  10. Security Architecture

  11. Modes • Transport Mode • Payload Encrypted • IP header is Intact • Routing is Intact • Tunnel Mode • New IP packet • New Routing • NW-NW Communication (tunnel)

  12. IPSec Packet

  13. Network Model

  14. IP tunnel

  15. Performance

  16. For Ad-Hoc Network

  17. IPSec for Ad-Hoc IP Cloud Subnet 1 Subnet 2

  18. Security

  19. Problems • Latency Increases • Overhead Increases • Throughput Decreases • Complexity Increases

  20. Conclusion • Ad-hoc Network uses various security methods • Do not violate existing protocol • IPSec is a new approach to secure IPv4 and IPv6 packets • Better approach can be used than IPSec
