Microarchitectural Attacks on Trusted Execution Environments
by
Keegan Ryan

Trusted Execution Environments (TEEs), like those based on ARM TrustZone or Intel SGX, intend to provide a secure way to run code beyond the typical reach of a computer’s operating system.

However, when trusted and untrusted code runs on shared hardware, it opens the door to the same microarchitectural attacks that have been exploited for years. This talk provides an overview of these attacks as they have been applied to TEEs, and it additionally demonstrates how to mount these attacks on common TrustZone implementations. Finally, we identify new techniques which allow us to peer within TrustZone TEEs with greater resolution than ever before.

Keegan Ryan has been a senior security consultant with NCC Group since June 2016, working primarily from Seattle. Keegan has experience with wireless protocols, reverse engineering embedded systems, TrustZone exploitation, virtualization, and cryptography. Prior to joining NCC Group, Keegan attended the California Institute of Technology, studying machine learning and applied mathematics.

This event will be videotaped by Panic. During event, remote users can interactively ask questions to speaker. You’ll need to sign in to Google Chat on the below Youtube URL. If you cannot attend, here’s the URL for the live streaming (and afterward, a copy of the video):

** post-EVENT BBQ:

The BBQ starts after the presentation ends. This month the chef will be Spooney. We’re planning hamburgers and some brats. I believe Ben is making Mulled Wine this month.

We’d welcome some additional dishes, as well as some decent hard ciders and beers. You can donate to the Black Lodge Research directly:
