%X Toral automorphisms mapping is a transform technology widely applied in digital image scramble.On certain condition the result can be reverted by controlling the transformation time because of the periodicity of the toral automorphisms transformation.In methods to this transformation,its application and generalization are mostly confined to the scrambling of the period and the huge time cost of the reverting.Therefore,the anti-toral transformation was studied.At first the transformation was proved to be bij...
