Class TPM2_ECDH_ZGen_REQUEST

java.lang.Object

tss.TpmStructure

tss.tpm.TPM2_ECDH_ZGen_REQUEST

All Implemented Interfaces:

TpmMarshaller

public class TPM2_ECDH_ZGen_REQUEST
extends TpmStructure

This command uses the TPM to recover the Z value from a public point (QB) and a private key (ds). It will perform the multiplication of the provided inPoint (QB) with the private key (ds) and return the coordinates of the resultant point (Z = (xZ , yZ) [hds]QB; where h is the cofactor of the curve).

TPM2_ECDH_ZGen_REQUEST

public TPM2_ECDH_ZGen_REQUEST(TPM_HANDLE _keyHandle,
                              TPMS_ECC_POINT _inPoint)

This command uses the TPM to recover the Z value from a public point (QB) and a private key (ds). It will perform the multiplication of the provided inPoint (QB) with the private key (ds) and return the coordinates of the resultant point (Z = (xZ , yZ) [hds]QB; where h is the cofactor of the curve).

Parameters:

_keyHandle - handle of a loaded ECC key Auth Index: 1 Auth Role: USER

_inPoint - a public key
