19C3::Porting GNU/Linux to Xbox

Who Am I ?

• I am a freelance hard & software developer/consultant with a broad range of experience in software engineering and cross-platform development. My focus is on embedded systems, lowlevel programming, realtime, IT-security and reverse engineering. I am living in Berlin, Germany.

Description

• Microsoft went to some lengths to ensure that only approved code could be run on their 'Microsoft-only' PC, the Xbox. The talk gives an overview of the Xbox hardware components, and a detailed background into the Xbox 'security' architecture of the Xbox, and how the chain of trust was defeated using custom hardware. Also covered in detail is Microsoft's recent changes to the boot crypto using Palladium-style hash methods, and how this was broken by our team. We will also talk briefly about TCPA/Palladium, the implications and its possible future as well as the process of porting Linux.
• In my part of the presentation you get a short overview of the GNU/Linux
porting process to the Xbox gaming system and its legal implications.
