Abstract: A method and a related apparatus provide a virtual trusted platform module (TPM). In an example embodiment, a virtual TPM service creates a virtual TPM for use in a processing system that contains a physical TPM. The virtual TPM service may store a key for the virtual TPM in the physical TPM. The virtual TPM service may then use the virtual TPM to provide emulated physical TPM features. In one embodiment, the virtual TPM service may use the virtual TPM to emulate a physical TPM for a virtual machine in the processing system. Other embodiments are described and claimed.

TL;DR: Xen, an x86 virtual machine monitor which allows multiple commodity operating systems to share conventional hardware in a safe and resource managed fashion, but without sacrificing either performance or functionality, considerably outperform competing commercial and freely available solutions.
ReVirt: enabling intrusion analysis through virtual-machine logging and replay
George W. Dunlap,Samuel T. King,Sukru Cinar,Murtaza A. Basrai,Peter M. Chen +4 more
- 09 Dec 2002
TL;DR: ReVirt removes the dependency on the target operating system by moving it into a virtual machine and logging below the virtual machine, and enables it to provide arbitrarily detailed observations about what transpired on the system, even in the presence of non-deterministic attacks and executions.

Copilot - a coprocessor-based kernel runtime integrity monitor
Nick L. Petroni,Timothy Fraser,Jesus Molina,William A. Arbaugh +3 more
- 13 Aug 2004
TL;DR: Copilot is a coprocessor-based kernel integrity monitor for commodity systems designed to detect malicious modifications to a host's kernel and has correctly detected the presence of 12 real-world rootkits within 30 seconds of their installation with less than a 1% penalty to the host's performance.
Property-based attestation for computing platforms: caring about properties, not mechanisms
Ahmad-Reza Sadeghi,Christian Stüble +1 more
- 20 Sep 2004
TL;DR: This paper points out the deficiencies of the attestation and sealing functionalities proposed by the existing specification of the Trusted Computing Group (TCG) and shows that these mechanisms can be misused to discriminate certain platforms and consequently the corresponding vendors.
