Austin Presents Keynote at HOST

Tuesday, May 2, 2017

C-FAR Director Todd Austin will present a keynote speech at the IEEE International Symposium on Hardware Oriented Security and Trust (HOST) in McLean, VA, May 2. His talk is entitled Establishing Hardware Trust: Challenges, Opportunities and (Im)possibilities and its abstract is:

Much of the future success of computing rests on our ability to establish trust in the hardware we build. In this talk, it will be argued that the approach taken to build secure hardware, that is adding security measures to thwart attacks, is fundamentally flawed because practical systems cannot be declared provably secure. Strangely, for security it is better to take away than to give. By removing the mechanisms used to implement attacks, it becomes possible to build large provably safe systems. The approach will be shown applied to code injection and timing-based side channels. While these "subtractive" approaches are powerful, it still remains to be seen if the techniques are composable and applicable to emerging hardware security threats.
