Title: “Trusted” Computing
Speaker: Dr. Kari Kostiainen, ETH Zurich
Date: Thursday, April 18, 2019
Location: Northeastern University, 655 Interdisciplinary Science & Engineering Complex (ISEC), 805 Columbus Avenue, Boston MA, 02120
Host: Aanjhan Ranganathan, Northeastern University
The release of Intel SGX popularized the notion of trusted computing. The main goal of trusted computing technologies like SGX is to enable protected applications on untrusted computing platforms. Instead of having to trust the entire platform that often consists of millions of lines of code written by developers who are not security experts, with trusted computing it is possible to deploy applications and services whose security relies only on the application code that can be small and carefully analyzed. Such reduction in trust assumptions is an attractive proposition.
In this talk, I will discuss how well SGX succeeds in this goal — and how much trust such we place on trusted computing technologies like SGX. I will provide an overview of some of our recent research projects where we examine the main capabilities of SGX (isolated execution, attestation and sealing), identify limitations in them, and propose solutions to address these problems. I will also discuss the challenges involved and the lessons learnt from building secure applications using SGX.
