量子会议密钥协议（QCKA）协议旨在允许多方就共享密钥达成一致，以防止计算上无限的对手。本文研究了一种高维QCKA协议，并证明了该协议在有限密钥情况下对任意、一般攻击的信息安全性。我们的证明技术对其他高维多方量子密码协议也有一定的借鉴意义。最后，我们在各种设置下对协议进行了评估，表明高维状态对QCKA协议有很大的好处。
Quantum Conference Key Agreement (QCKA) protocols are designed to allow multiple parties to agree on a shared secret key, secure against computationally unbounded adversaries. In this paper, we consider a high-dimensional QCKA protocol and prove its information theoretic security against arbitrary, general, attacks in the finite-key scenario. Our proof technique may be useful for other high-dimensional multiparty quantum cryptographic protocols. Finally, we evaluate the protocol in a variety of settings, showing that high-dimensional states can greatly benefit QCKA protocols.
