Grand Challenges in Mission Critical Networking

• Deepa Kundur
• Electrical Computer Engineering
• Texas AM University

2
Secure services in the face of partial network
disruption

• Insufficient to borrow existing network security
  approaches for MCNs new paradigms needed
• Network disruption
• Loss of key management infrastructure
• Loss of critical communication links
• Attacks on sensing
• Research thrusts
• Enciphering without the use of secret keys (hide
  in the interference, distribute information)
• Hybrid communication paradigms
• Interaction of signal processing and cryptography

Detection and Reaction to Denial-of-Service
Attacks

• DoS attacks
• DoS attacks are quite broad including attacks on
  sensing, attacks on connectivity, stealthy
  information poisoning
• Detection and reaction strategies required
• New network architectures can discourage common
  DoS attacks
• Research thrusts
• Mitigation approaches against DoS attacks
• Topology reconfiguration for DoS recovery
• Employ multimodal data for detection of attacks

4
Audit Trails and MCN Forensics

• To quickly and effectively recover from attacks,
  network must trace source of information and data
  corruption
• The data-centric nature of sensor surveillance
  systems has potential for piggybacking forensic
  data that is robust to aggregation and data
  manipulation
