Experimenting with TCPA/TCG Hardware, Or: How I Learned to Stop Worrying and Love The Bear
Technical Report TR2003-476, Department of Computer Science, Dartmouth College.
Consequently, we began an experiment to see if (in the absence of a Non-Disclosure Agreement) we could use this hardware to transform a desktop Linux machine into a virtual secure coprocessor: more powerful but less secure than higher-end devices. This experiment has several purposes: to provide a new platform for secure coprocessor applications, to see how well the TCPA/TCG approach works, and (by working in open source) to provide a platform for the broader community to experiment with alternative architectures in the contentious area of trusted computing.
This paper reports what we have learned so far: the approach is feasible, but effective deployment requires a more thorough look at OS security.
