摘要:

文章利用量子傅里叶变换,提出一个可认证多方量子秘密共享协议。在该协议中,d级单粒子作为信息载体在秘密拥有者和代理人之间传输,代理人利用两类广义Pauli算子进行编码操作,拥有者通过对信号粒子的测量得到秘密。在重构过程中,当且仅当所有代理人协作才能恢复出该秘密。同时,文章结合经典Hash函数对代理人身份进行认证,并将身份认证过程与信道窃听检测结合起来,提高协议的检测效率。文章对协议的安全性和认证性进行了详细的讨论,证明该协议在理论上是安全的。

Abstract:

Utilizing quantum Fourier transformation, this paper proposes an authenticated multiparty quantum secret sharing protocol. In the protocol, d-level single particle is transmitted as the information carrier between the secret owner and all agents. The agents encode their private messages on these traveled particles by two kinds of generalized Pauli operators, and the owner measures the particles and obtains his secret. In the process of reconstruction, the secret can be recovered if and only if all agents collaborate. This paper uses the classic Hash function to authenticate the agent’s identity, and combines the authentication process with the channel eavesdropping detection to improve the detection efficiency of the protocol. This paper discusses the security and authentication of the protocol in detail, which shows that the proposed protocol is safe in theory.

Key words: quantum secret sharing, d-level single particle, identity authentication
