All Implemented Interfaces:

TpmMarshaller

public class RewrapResponse
extends RespStructure

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.
