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:
“The human mind is capable of excitement without the application of gross and violent stimulants; and he must have a very faint perception of its beauty and dignity who does not know this.”
—William Wordsworth (1770–1850)
“If you would be a favourite of your king, address yourself to his weaknesses. An application to his reason will seldom prove very successful.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
“Great abilites are not requisite for an Historian; for in historical composition, all the greatest powers of the human mind are quiescent. He has facts ready to his hand; so there is no exercise of invention. Imagination is not required in any degree; only about as much as is used in the lowest kinds of poetry. Some penetration, accuracy, and colouring, will fit a man for the task, if he can give the application which is necessary.”
—Samuel Johnson (1709–1784)
