Interface PairingPreProcessing

All Superinterfaces:

PreProcessing

public interface PairingPreProcessing
extends PreProcessing

If it is known in advance that a particular element will be paired several times then time can be saved in the long run by using preprocessing. The, this interface is used to compute the pairing function when preprocessing information has been compute before on the first input which is so fixed for each instance of this interface.

Method Detail

pairing

Element pairing(Element in2)

Compute the pairing where the second argument is in2. The pre-processed information are used for a fast computation

Parameters:

in2 - the second pairing function argument.

Returns:

an element from GT whose value is assigned by this map applied to in1 and in2.
