# SNP
|
||
|
|
|
||
|
|
Attestation based on TPM and SEV-SNP attestation.
|
||
|
|
The TPM is used to generate runtime measurements and signed by an attestation key that can be verified using the SEV-SNP attestation report.
|
||
|
|
|
||
|
|
# Issuer
|
||
|
|
|
||
|
|
Generates a TPM attestation using an attestation key saved in the TPM.
|
||
|
|
Additionally loads the SEV-SNP attestation report and AMD VCEK certificate chain, and adds them to the attestation document.
|
||
|
|
|
||
|
|
# Validator
|
||
|
|
|
||
|
|
Verifies the attestation key used by first verifying the VCEK certificate chain and the SNP attestation report.
