论文摘要
量子会议密钥协议（CKA）是多方建立共同秘密密钥的加密工作。尽管双分量量子键分布协议在CKA的背景下也很有用，但多方协议允许更有效地生成必要的相关性，因此在量子网络的背景下可以很好地查看。在未来的量子网络中，以匿名方式生成秘密钥匙对于那些不仅要保留其共享密钥秘密而且保护自己的身份的当事方至关重要，例如在吹口哨的背景下。 在本文中，我们为匿名量子会议密钥协议提供了第一个协议，并使用四片Greenberger-Horne-Zeilinger（$ \ MATHRM {GHz} $）态度证明了它。
Quantum Conference Key Agreement (CKA) is a cryptographic effort of multiple parties to establish a shared secret key. While bipartite quantum key distribution protocols are also useful in the context of CKA, multipartite protocols allow for a more efficient generation of the necessary correlations and are therefore viewed favorably in the context of quantum networks. In future quantum networks, generating secret keys in an anonymous way is of tremendous importance for parties that do not only want to keep their shared key secret but also protect their own identity, e.g. in the context of whistle-blowing. In this paper we provide the first protocol for Anonymous Quantum Conference Key Agreement and demonstrate it using four-photon Greenberger-Horne-Zeilinger ($\mathrm{GHZ}$) states.
