Class ECDH_ZGenResponse

java.lang.Object

tss.TpmStructure

tss.tpm.ECDH_ZGenResponse

All Implemented Interfaces:

TpmMarshaller

public class ECDH_ZGenResponse
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).
