Abstract

Security is an emerging topic in the field of mobile and embedded platforms. The Trusted Computing Group (TCG) has outlined one possible approach to mobile platform security by recently extending their set of Trusted Computing specifications with Mobile Trusted Modules (MTMs). The MTM specification [13] published by the TCG is a platform independent approach to Trusted Computing explicitly allowing for a wide range of potential implementations. ARM follows a different approach to mobile platform security, by extending platforms with hardware supported ARM TrustZone security [3] mechanisms. This paper outlines an approach to merge TCG-style Trusted Computing concepts with ARM TrustZone technology in order to build an open Linux-based embedded trusted computing platform.
