| Abstract: | A scalable protocol for multiparty quantum secret splitting with collective eavesdropping-check is proposed by using Einstein-Podolsky-Rosen pairs. We analyze the security of this protocol and prove that it can stand against some possible attacks in an ideal condition. Meanwhile, this protocol utilizes quantum dense coding to achieve a high intrinsic efficiency and source capacity. Moreover, only Bell-state measurement and local unitary operations are required, which makes this protocol more convenient from an applied point of view. |
