Field Detail

isSender_

protected boolean isSender_
Option for generating the key (called a TEK). The value is TRUE if the sender (originator) generates the TEK, FALSE if the recipient is regenerating the TEK.

randomA_

protected byte[] randomA_
The Ra data.

randomB_

protected byte[] randomB_
The Rb data.

publicData_

protected byte[] publicData_
The other party's KEA public key value.
Constructor Detail

KEADeriveParameters

public KEADeriveParameters(boolean isSender,
                           byte[] randomA,
                           byte[] randomB,
                           byte[] publicData)
Create a new KEADeriveParameters object with the given attributes.
Parameters:
isSender - Option for generating the key (called a TEK). The value is TRUE if the sender (originator) generates the TEK, FALSE if the recipient is regenerating the TEK.
randomA - The random data Ra.
randomB - The random data Rb.
publicData - The other party's KEA public key value.
Method Detail

clone

public java.lang.Object clone()

Overrides:
clone in class java.lang.Object
Returns:
A clone of this object.

getPKCS11ParamsObject

public java.lang.Object getPKCS11ParamsObject()
Get this parameters object as an object of the CK_KEA_DERIVE_PARAMS class.
Specified by:
getPKCS11ParamsObject in interface Parameters
Returns:
This object as a CK_KEA_DERIVE_PARAMS object.

getPublicData

public byte[] getPublicData()
Get the other party's KEA public key value.
Returns:
The other party's KEA public key value.

getRandomA

public byte[] getRandomA()
Get the random data Ra.
Returns:
The random data Ra.

getRandomB

public byte[] getRandomB()
Get the random data Rb.
Returns:
The random data Rb.

isSender

public boolean isSender()
Get the option for generating the key (called a TEK).
Returns:
True if the sender (originator) generates the TEK, false if the recipient is regenerating the TEK.

setPublicData

public void setPublicData(byte[] publicData)
Set the other party's KEA public key value.
Parameters:
publicData - The other party's KEA public key value.

setRandomA

public void setRandomA(byte[] randomA)
Set the random data Ra.
Parameters:
randomA - The random data Ra.

setRandomB
