提出了一个用4个量子态实现的多方与多方之间的量子秘密共享方案,并证明此方案对用多光子信号的特洛伊马攻击、用Einstein-Podolsky-Rosen对的伪信号攻击、单光子攻击以及不可见光子攻击是安全的.另外,给出了不忠实者使用任意两粒子纠缠态伪信号攻击方法窃听秘密信息平均成功概率的上界。
A scheme of quantum secret sharing between multi-parties and multi-parties using four quantum states is proposed. The scheme is also validated for Trojan horse attacks using multiphoton signals, spurious signal attacks using Einstein-Podolsky-Rosen pair, single-photon attack And the invisible photon attack is safe.In addition, the upper bound of the average probability of success of the eavesdropping on the secret information by the unfaithful person using any two-particle entangled state pseudo-signal attack method is given.
