05. Future of Autonomous Biosecurity Sensing

In the future, it is reasonable to expect huge swarms of low cost drones that are scanning for biosecurity etc.

Assume a central base station that controls the paths of the drones. How would you would violate the security of the drones?

• Jam signal
  • Frequency hopping?
  • P2P communication will make jamming more difficult
  • If close enough, can locate self relative to other drones visually
• GPS spoofing?
  • Or just jam GPS
    • Use local map and determine position using landmarks, inertial sensors etc.
  • Gradually shift position to cause them to crash?
• Replay attack?
  • Timestamp packets, max age
  • P2P sharing of latest command index/timestamp in system; if one drone can hear the original signal, they can share it with others to prevent replays
• Spoof commands
  • Sign packets with public key encryption
  • Commands from base station sent peer to peer so jamming will be difficult
• PKI to establish symmetric key
  • Shoot down a drone and extract keys?
  • Hardware security modules; no way to access key
