new Plugins for algebraic attack on Stream cipher :
1) compute XZ: compute the sets XZ that one need to generate a system of equations for algebraic attack
2) compute annihilators: compute annihilators of the sets XZ (Z-funktions) and annihilators for boolean function
3) system of equations: use Z-functions and known keystream to generate a system of equations that can be used for an algebraic attack
