OSLO: Improving the Security of Trusted Computing

Abstract
In this paper we describe bugs and ways to attack trusted
computing systems based on a static root of trust such as
Microsoft's Bitlocker. We propose to use the dynamic root of
trust feature of newer x86 processors as this shortens the
trust chain, can minimize the Trusted Computing Base of
applications and is less vulnerable to TPM and BIOS attacks.
To support our claim we implemented the Open Secure LOader
(OSLO), the first publicly available bootloader based on AMDs
skinit instruction.
