I dont understand,,, what does it mean Attestation services.
This is a mechanism that allows software to identify that software is in a trusted configuration state without unauthorized modifications, for instance:
A client machine is running a trusted OS, within the configuration state specified by a security policy. When the OS boots up, it will generate a certificate and send that to an attestation server. The attestation server compares the current configuration (in the file presented by the OS) to a preconfigured policy, to make sure the current configuration is acceptable and trustworthy.

It is clear, Thanks for your reply.
