Class TPM2_Rewrap_REQUEST

java.lang.Object

tss.TpmStructure

tss.tpm.TPM2_Rewrap_REQUEST

All Implemented Interfaces:

TpmMarshaller

public class TPM2_Rewrap_REQUEST
extends TpmStructure

This command allows the TPM to serve in the role as a Duplication Authority. If proper authorization for use of the oldParent is provided, then an HMAC key and a symmetric key are recovered from inSymSeed and used to integrity check and decrypt inDuplicate. A new protection seed value is generated according to the methods appropriate for newParent and the blob is re-encrypted and a new integrity value is computed. The re-encrypted blob is returned in outDuplicate and the symmetric key returned in outSymKey.

Constructor Detail

TPM2_Rewrap_REQUEST

public TPM2_Rewrap_REQUEST(TPM_HANDLE _oldParent,
                           TPM_HANDLE _newParent,
                           TPM2B_PRIVATE _inDuplicate,

This command allows the TPM to serve in the role as a Duplication Authority. If proper authorization for use of the oldParent is provided, then an HMAC key and a symmetric key are recovered from inSymSeed and used to integrity check and decrypt inDuplicate. A new protection seed value is generated according to the methods appropriate for newParent and the blob is re-encrypted and a new integrity value is computed. The re-encrypted blob is returned in outDuplicate and the symmetric key returned in outSymKey.

Parameters:

_oldParent - parent of object Auth Index: 1 Auth Role: User

_newParent - new parent of the object Auth Index: None

_inDuplicate - an object encrypted using symmetric key derived from inSymSeed

_name - the Name of the object being rewrapped

_inSymSeed - the seed for the symmetric key and HMAC key needs oldParent private key to recover the seed and generate the symmetric key

TPM2_Rewrap_REQUEST
