A Hybrid Approach to Secure Function Evaluation Using SGX

1 code implementation3 May 2019 Joseph I. Choi, Dave 'Jing' Tian, Grant Hernandez, Christopher Patton, Benjamin Mood, Thomas Shrimpton, Kevin R. B. Butler, Patrick Traynor

We describe SGX-enabled SFE protocols (modeling the enclave as an oracle), and formalize the strongest-possible notion of 2P-SFE for our setting.

Practical Hidden Voice Attacks against Speech and Speaker Recognition Systems

no code implementations18 Mar 2019 Hadi Abdullah, Washington Garcia, Christian Peeters, Patrick Traynor, Kevin R. B. Butler, Joseph Wilson

In this paper, we break these dependencies and make hidden command attacks more practical through model-agnostic (blackbox) attacks, which exploit knowledge of the signal processing algorithms commonly used by VPSes to generate the data fed into machine learning systems.
