- 1. NTXISSA Cyber Security Conference – November 10-11, 2017 @NTXISSA #NTXISSACSC5 [Session Title] [Presenter] [Position] [Institution] [Date]
- 3. About me • University of North Texas Alum • Class of 2017 • Majored in Computer Engineering • Team Leader for Senior Design project for NASA • President of UNT’s Club for Cyber Security • National Cyber League • Collegiate Cyber Defense Competition • Goldman Sachs Analyst 2017 NAPA • GS 2016 Summer Analyst (Intern) #NTTXISSACSC5 Abusing Protocols for Dynamic Addressing in Spaces 32017-Nov-11th
- 4. Team IRIS • Jacen R Kohler • Tyler Alvarez • Alex Fatum #NTTXISSACSC5 Abusing Protocols for Dynamic Addressing in Spaces 42017-Nov-11th
- 5. How did I get a NASA Project? Texas Space Grant Consortium • Educational wing for NASA in Texas • Open to all college students in Texas • Other stated have equivilant programs #NTTXISSACSC5 Abusing Protocols for Dynamic Addressing in Spaces 52017-Nov-11th
- 6. Current Situation Internet in space uses static IPv4 addresses Static addressing requires manually assigning addresses Static addressing is not fault tolerant duplicates are possible The constantly varying propagation delays & line interfere with traditional network handshakes #NTTXISSACSC5 Abusing Protocols for Dynamic Addressing in Spaces 62017-Nov-11th
- 7. Current Situation The current Tracking and Data Relay Satellite (TDRS) System are merely repeaters and amplifies and have no routing capabilities #NTTXISSACSC5 Abusing Protocols for Dynamic Addressing in Spaces 72017-Nov-11th
- 8. The Problem The process should be automated aka… Dynamic Addressing Just like your phone on a coffee shop’s wifi A protocol like this already exists Dynamic Host Configuration Protocol (DHCP) #NTTXISSACSC5 Abusing Protocols for Dynamic Addressing in Spaces 82017-Nov-11th
- 9. How to Solve this problem Simulate a space network, down here on Earth including… propagation delay line-of-sight signal blocking adequate complexity (enough parts to be realistic) Find a way to implement DHCP in the simulated space network #NTTXISSACSC5 Abusing Protocols for Dynamic Addressing in Spaces 92017-Nov-11th
- 10. #NTTXISSACSC5 Abusing Protocols for Dynamic Addressing in Spaces 102017-Nov-11th Adequate Complexity •Simulate a space network on earth •10x Raspberry Pi 3 •Mission Control Center •3x TDRS •TDRS5, TDRS7, &TDRS9 •3x Spacecraft • ISS, Hubble, Orion •3x EVA Suits
- 11. #NTTXISSACSC5 Abusing Protocols for Dynamic Addressing in Spaces 112017-Nov-11th Adequate Complexity
- 12. #NTTXISSACSC5 Abusing Protocols for Dynamic Addressing in Spaces 122017-Nov-11th Adequate Complexity • Pull TLE data from CelesTrak • Two Line Element (TLE) • 3000 TLE data in the file that gets parsed • Search for orbital element we need • Extract the 6 Keplerian Elements from TLE • 6 Keplerian elements are like an address • Allow us to calculate time based locations • Past, present, or future
- 13. #NTTXISSACSC5 Abusing Protocols for Dynamic Addressing in Spaces 132017-Nov-11th Simulated Space Network • One way link to TDRS in GeoSynchronous orbit takes • Simulation must emulate these delays to be realistic
- 14. #NTTXISSACSC5 Abusing Protocols for Dynamic Addressing in Spaces 142017-Nov-11th Simulated Space Network (cont.) • Delays will be simulated using existing open source tools designed for network testing • tcconfig +312.432ms 149460120 0 Hold for delay Epoch time received Packet Ingress ( distance / speed of light ) + time of insert +312.437ms 149460120 1 +312.443ms 149460120 2 +312.449ms 149460120 3 +312.452ms 149460120 4

- 17. #NTTXISSACSC5 Abusing Protocols for Dynamic Addressing in Spaces 172017-Nov-11th DHCP • Discover • Spacecraft announces its presence • Offer • DHCP offers several available addresses • Request • Spacecraft requests an offered addresses • Acknowledge • DHCP assigns requested address • DHCP from Earth takes ~112ms • DHCP from TDRS takes ~56ms • 50% time savings
- 18. #NTTXISSACSC5 Abusing Protocols for Dynamic Addressing in Spaces 182017-Nov-11th DHCP (cont.) • Offer (predicted) • DHCP offers only one address • Request • Spacecraft requests the address offered • Acknowledge (pipelined) • DHCP pre-empts the acknowledgement • Traditional DHCP takes ~112ms • Pipelined DHCP takes ~28ms • 75% time savings • Pipeline DHCP from TDRS takes ~12ms • 87.5% time savings
