What are integrity measurements?
Integrity measurement is a technique to enable a party to query the integrity status of software running on a platform, e.g., through attestation challenges. Several integrity measurement mechanisms have been proposed and developed.
What is TPM state?
A Trusted Platform Module (TPM) is a specialized chip on an endpoint device that stores RSA encryption keys specific to the host system for hardware authentication. The term TPM is sometimes used in reference to the set of specifications applicable to TPM chips.
How do you measure success in integrity?
The integrity of a business can be measured by its commitment to the community. It is a good neighbor that implements safety standards to protect the environment. The business finds ways to contribute to the community needs financially and through volunteer projects.
How do you measure leadership integrity?
Integrity in leaders refers to being honest, trustworthy, and reliable. Leaders with integrity act in accordance with their words (i.e. they practice what they preach) and own up to their mistakes, as opposed to hiding them, blaming their team, or making excuses.
What is a platform configuration?
Platform Configuration Registers (PCRs) are one of the essential features of a TPM. Their prime use case is to provide a method to cryptographically record (measure) software state: both the software running on a platform and configuration data used by that software.
How is TPM used to ensure platform integrity?
Help ensure platform integrity by taking and storing security measurements. The most common TPM functions are used for system integrity measurements and for key creation and use. During the boot process of a system, the boot code that is loaded (including firmware and the operating system components) can be measured…
Is the TPM a monitor or control device?
The TPM does not measure, monitor or control anything The TPM is a passive device in the system The TPM has no way of knowing what was measured Measurements are made by host software and sent to the TPM
How is a measurement stored in a TPM?
This means whenever a measurement is sent to a TPM, the hash of the concatenation of the current value of a PCR and the new measurement is stored (i.e. new_value = Hash (old_value || new_measurement) ). Obviously, there’s a beginning to all of this:
How is TPM used for platform device authentication?
Use TPM technology for platform device authentication by using the TPM’s unique RSA key, which is burned into itself. Help ensure platform integrity by taking and storing security measurements. The most common TPM functions are used for system integrity measurements and for key creation and use.
