public class PFlashKeyGenParameterSpec

extends java.lang.Object

implements AlgorithmParameterSpec

This class provides the specification of the parameters used by the PFlashKeyPairGenerator.

The default values for the parameters are :

degree of extension m	=	4
field polynomial of GF(2m)	=	X4 + X + 1
extension degree of E/K	=	96
α	=	32
r	=	32
s	=	1
