This paper describes three practical techniques for authenticating the code and other execution state of an operating system using the services of the TPM and a hypervisor. The techniques trade off detailed reporting of the OS code and configuration with the manageability and comprehensibility of reported configurations. Such trade-offs are essential because of the complexity and diversity of modern general purpose operating systems makes simple code authentication schemes using code hashes or certificates infeasible.
