Class TPM2_Commit_REQUEST

  • All Implemented Interfaces:
    TpmMarshaller
    public class TPM2_Commit_REQUEST
extends ReqStructure
    TPM2_Commit() performs the first part of an ECC anonymous signing operation. The TPM will perform the point multiplications on the provided points and return intermediate signing values. The signHandle parameter shall refer to an ECC key and the signing scheme must be anonymous (TPM_RC_SCHEME).
