论文摘要
量子会议密钥协议（QCKA）协议旨在允许多方就共享的秘密密钥达成共识，并确保对抗对手的计算无限的对手。在本文中，我们考虑了一个高维QCKA协议，并在有限键方案中针对任意，一般性攻击证明其信息理论安全性。我们的证明技术可能对其他高维多方量子加密协议有用。最后，我们在各种设置中评估该协议，表明高维状态可以极大地使QCKA协议受益。
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 multi-party quantum cryptographic protocols. Finally, we evaluate the protocol in a variety of settings, showing that high-dimensional states can greatly benefit QCKA protocols.
