UINT64 | MonotonicCount |
WIN_CERTIFICATE_UEFI_GUID | AuthInfo |
Provides the authorization for the firmware image operations. It is a signature across the image data and the Monotonic Count value. Caller uses the private key that is associated with a public key that has been provisioned via the key exchange. Because this is defined as a signature, WIN_CERTIFICATE_UEFI_GUID.CertType must be EFI_CERT_TYPE_PKCS7_GUID.
It is included in the signature of AuthInfo. It is used to ensure freshness/no replay. It is incremented during each firmware image operation.
