Application
PCR values are available both locally and remotely. Furthermore, the TPM has the capability to digitally sign the PCR values (i.e., a PCR Quote) so that any entity can verify that the measurements come from, and are protected by, a TPM, thus enabling Remote Attestation to detect tampering, corruption, and malicious software. Additionally, those values can be used to identify the execution environment (the particular BIOS version, OS level, configuration, etc.) and compare them to their own lists of known-good values to further categorize the platform. This ability to evaluate and assign trust levels to platforms is known as Trusted Compute Pools.
Some examples of how Trusted Compute Pools are being used:
- Isolation – the ability to control if a platform connects to the production network or is quarantined based on its trust level or failure to pass its launch control policy.
- Trust Based Policy – such as restricting critical apps to only execute on platforms that meet a specified trust level
- Compliance and Auditing – Demonstrating that critical, personal, or sensitive data has only been processed on platforms that meet trust requirements

Famous quotes containing the word application:
“It would be disingenuous, however, not to point out that some things are considered as morally certain, that is, as having sufficient certainty for application to ordinary life, even though they may be uncertain in relation to the absolute power of God.”
—René Descartes (1596–1650)
“My business is stanching blood and feeding fainting men; my post the open field between the bullet and the hospital. I sometimes discuss the application of a compress or a wisp of hay under a broken limb, but not the bearing and merits of a political movement. I make gruel—not speeches; I write letters home for wounded soldiers, not political addresses.”
—Clara Barton (1821–1912)
““Five o’clock tea” is a phrase our “rude forefathers,” even of the last generation, would scarcely have understood, so completely is it a thing of to-day; and yet, so rapid is the March of the Mind, it has already risen into a national institution, and rivals, in its universal application to all ranks and ages, and as a specific for “all the ills that flesh is heir to,” the glorious Magna Charta.”
—Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)
