CESG Seminar: Exo-Core — Software-Defined Hardware-Security

Mohit Tiwari – University of Texas at Austin

Abstract: Confinement is a fundamental security primitive. The ability to put private data in a box and ship the box to run untrusted code in an untrusted data center can transform systems security and expand the use of cloud services to regulated data. However, untrusted applications are hard to confine — we show that using only meta-data about the computation, a malicious process can leak secrets at hundreds of kilo-bits per second on machines today. Closing such leaks in the past has followed a piece-meal approach of closing individual channels. In this talk, we propose that exposing the micro-architecture to software can enable flexible defenses to a large class of vulnerabilities, and show that software solutions can implement efficient and verifiable solutions to hardware-security problems.


Bio: Mohit Tiwari received his PhD from UCSB (2011) and joined UT Austin as an Assistant Professor in Fall 2013. His research enables privacy for end-users through information leak-free containers — such containers can be used to create trustworthy computing services using untrusted data centers and vulnerable applications — and through anomaly detection across the computing stack. Professor Tiwari’s research has received the NSF Career Award (2015), Best Paper Awards (ASPLOS’15, PACT’09), IEEE Micro Top Picks (2010, 2014 Honorable Mention), and industry research awards from Google and Qualcomm.
