基于秘密认证的可验证量子秘密共享协议

该文针对量子秘密共享协议难以抵抗内部成员欺骗攻击的问题，采用秘密认证的方法提出可验证量子秘密共享协议的一般性模型，基于Bell态双粒子变换提出一种新验证算法，并以此给出一个新的可验证量子秘密共享协议。与现有的量子秘密共享协议的验证算法相比，新验证算法既能有效抵抗内部成员欺骗攻击等典型的攻击策略，又可大幅提升协议效率，而且可以与现有量子秘密共享协议相结合，具备很好的可扩展性。

Verifiable Quantum Secret Sharing Protocol Based on Secret Authentication

To solve the problem that Quantum Secret Sharing (QSS) protocol is difficult to resist inner-cheating attack, by utilizing the method of secret message authentication to present a general model of verifiable quantum secret sharing protocols, a new verification algorithm is proposed based on the two-particle transform of Bell states, and then a new verifiable quantum secret sharing protocol is proposed. Compared with the verification algorithms of the existing verifiable quantum secret sharing protocol, the new verification algorithm can not only resist effectively the typical attack strategies such as the inner-cheating attack, but also improves greatly the efficiency of the protocol, and has good scalability which can be combined with the existing quantum secret sharing protocols.
