An apparatus and method for angle rotation is disclosed to rotate a complex input by the angle \u03b8 to produce a rotated complex output signal. The array has pages that are not one continuous array row. An execution of the first and second phases is undistinguishable by the data power analysis attacks. A raised feature of the liftglass assembly, preferably having a color and surface finish that is coordinated with a painted body surface, defines a step that is substantially aligned with the vehicle beltline to thereby aesthetically substantially continue the vehicle beltline across the rear of the vehicle.
