Class TPM2_PolicySigned_REQUEST

  • All Implemented Interfaces:
    TpmMarshaller
    public class TPM2_PolicySigned_REQUEST
extends ReqStructure
    This command includes a signed authorization in a policy. The command ties the policy to a signing key by including the Name of the signing key in the policyDigest

    • Field Detail

      • authObject

        public TPM_HANDLE authObject
        Handle for a key that will validate the signature Auth Index: None

      • policySession

        public TPM_HANDLE policySession
        Handle for the policy session being extended Auth Index: None

      • nonceTPM

        public byte[] nonceTPM
        The policy nonce for the session This can be the Empty Buffer.

      • cpHashA

        public byte[] cpHashA
        Digest of the command parameters to which this authorization is limited This is not the cpHash for this command but the cpHash for the command to which this policy session will be applied. If it is not limited, the parameter will be the Empty Buffer.

      • policyRef

        public byte[] policyRef
        A reference to a policy relating to the authorization may be the Empty Buffer Size is limited to be no larger than the nonce size supported on the TPM.

      • expiration

        public int expiration
        Time when authorization will expire, measured in seconds from the time that nonceTPM was generated If expiration is non-negative, a NULL Ticket is returned. See 23.2.5.

      • auth

        public TPMU_SIGNATURE auth
        Signed authorization (not optional) One of: TPMS_SIGNATURE_RSASSA, TPMS_SIGNATURE_RSAPSS, TPMS_SIGNATURE_ECDSA, TPMS_SIGNATURE_ECDAA, TPMS_SIGNATURE_SM2, TPMS_SIGNATURE_ECSCHNORR, TPMT_HA, TPMS_SCHEME_HASH, TPMS_NULL_SIGNATURE.
