Trusted Computing is a significant paradigm shift in the design of networked computing devices, and hardware support for it is quickly becoming commonplace. Many authors have observed the potential for this technology to offer significant and substantial benefits to grid, cloud, and other models of distributed computing, but so far relatively few of these have been realized. Much of the discussion of the field in the popular media has been dominated by discussion of a particular kind of multimedia rights management, and has been characterized by a certain degree of mis-information, and out-of-date material.

This tutorial aims to give a thorough overview of the motivation for this approach, the technical capabilities of the trusted computing technologies, and their connection to whole system virtualization. We will end with a more discursive exploration of the realistic potential for their prototyping and deployment in eScience applications.
