摘　　要：以d维纠缠交换为技术手段,提出了一个(t,n)门限量子秘密共享方案。该方案执行t次d维纠缠交换,秘密影子聚合于重建者的V_1粒子中。重建者测量该粒子,可重建出共享的秘密。通过安全性分析可知,提出的方案能够抵抗截获—重放攻击、纠缠—测量攻击、合谋攻击和伪造攻击。性能分析表明,相较于其他现有类似量子秘密共享方案,该方案具有更好的灵活性、实用性和普适性,而且总的计算和测量所花费的开销是最低的。This paper proposed a ( t,n ) threshold quantum secret sharing scheme by means of d -dimensional entanglement swapping. The proposed scheme executed t times of d -dimensional entanglement swapping, which aggregated secret shadows into V 1 particle of the reconstructor. Finally, the reconstructor measured this particle to reconstruct the original secret. Security analysis shows that the proposed scheme can resist intercept-resend, entangle-measure, collusion and forgery attacks. By comparison with other similar schemes in performance, the proposed scheme is more flexible, practical and universal. In addition, its total overheads of computation and measurement are lowest in current similar quantum secret sharing schemes.
