Dan Boneh - SaTC Cyber Cafe

  1. 1. Rubber hose resistant cryptographyH. Bojinov, D. Sanchez, P. Reber, D. Boneh, P. Lincoln
  2. 2. Rubber hose attacksProblem: authenticating users at the entrance to a secure facilityCurrent solutions:• Smartcards: can be stolen• Biometrics: can be copied or spoofed• Passwords: can be extracted with a rubber hoze Is there a non-extractable credential?
  3. 3. The human memory system• Hippocampus: conscious learning – Learns from single examples• Basal ganglia: “implicit learning” – Learns from many repeated samplesOur work: use implicit learning to teach a credential – Credential can be tested at authentication time – … but credential is not consciously accessible !!
  4. 4. Implicitly learning a credential http://brainauth.comParticipants exhibit essentially no recognition after training
