We propose a novel strategy named basis-splitting scheme to split the intercepted quanta into several portions based on different bases,for eavesdropping in the process of quantum cryptography.Compared with interceptresend strategy,our simulation results of the basis-splitting scheme under the non-ideal condition show a greater performance,especially with the increase of the length of shifted bits.Consequently our scheme can aid eavesdropper to gather much more useful information.
