Class TcTssValidation

Object
  TcTssValidation

public class TcTssValidation
extends Object

The TcTssValidation structure provides the ability to verify signatures and validation digests built over certain TPM command parameters. These parameters (i.e. structures) are defined in TPM 1.2 specification. The caller must provide some random data (externalData_) as input, which is included in the signature/digest calculation.
The following TSP functions use this structure:

• TPM_CertifySelfTest
• TPM_GetCapabiltiySigned
• TPM_LoadMaintenancePubKey
• TPM_CheckMaintenancePubKey
• TPM_CertifyKey
• TPM_CreateEndoresementKey
• TPM_GetPubEndorsementKey
• TPM_CreateRevocableEndorsementKey
• TPM_Quote
• TPM_Quote2
• Context_CloseSignTransport

If the validation of the signature/digest should be done by the TSP itself, a null pointer must be passed to these methods. In this case the TSP generates its own random data to be included in the signature/digest (externalData_).
