A meeting about hidden services in Washington DC happening early in July 2015.

Dates

From the 9th of July to the 13th (and more?).

Topics

• kernelcorn's OnioNS [asn] [kernelcorn] [dgoulet]
  • design
  • compatibility with 224 and Donncha's work
  • required modifications to Tor
  • installation best practices
  • how to actually deploy it realistically?
• OnionDNS (oniondns.org, distinct from OnioNS, just as an FYI)
• Hidden Service fingerprinting defenses (the USENIX paper) [kernelcorn] [dgoulet] [Aaron Johnson] [Rob]
• Direct onion services [dgoulet] [Aaron Johnson] [syverson] [Rob]

  • Are guards, introduction points, and rendezvous points needed?
• Guard discovery attacks [asn] [Aaron Johnson] [special] [syverson] [Rob]
  • How to make the attacks harder for hidden services that care
• Next Generation Hidden Services [asn] [kernelcorn] [dgoulet] [Aaron Johnson] [special] [syverson] [Rob]
