content_copy zoom_out_map
request system integrity attestation (pcr-index pcr number | nonce-value | tpm-name)

Description

The Attester is a device on the network that provides evidence to the Verifier on demand. The first part of that evidence is a signed collection of the TPM's Platform Configuration Registers (PCRs) called a TPM Quote. To ensure the freshness of the quote, the Verifier sends a random nonce to the Attester to include in the TPM Quote.

Options

nonce-value	Defines a base-64 encoded 20 byte random hex value. A cryptographically generated random number which should not be predictable prior to its issuance from a random number generation function. The random number MUST be derived from an entropy source external to the Attester.
pcr-index	The numbers/indexes of the PCRs. At the moment this is limited to 32 items. (0..31)
tpm-name	Unique system generated name for a TPM on a device.
