Attacking Intel Trusted Execution Technology (Blackhat DC)

Vivek Ramachandran

Recommended Posts

"Attacking Intel Trusted Execution Technology" was a talk given by Rafal Wojtczuk & Joanna Rutkowska from InvisibleThings in Blackhat DC this year. In their talk they describe what Intel® TXT is, how it works, and how it can be used to build more secure systems. They also show, however, weaknesses in current TXT implementations and how they can be practically exploited. They also show a working exploit code against tboot - Intel's implementation of trusted boot process for Xen and Linux.
