论文摘要
量子密钥协议要求所有参与者一起恢复共享密钥，因此抵制参与者攻击至关重要。在本文中，我们提出了基于六分群集状态的可验证的多方量子密钥协议协议。该协议将保留六量集群状态的某些子序列的可验证分销商介绍，因此参与者无法提前获得共享密钥。此外，共享密钥的正确性和同时性由受信任的设计组合仪和同型哈希功能保证。此外，安全分析表明，新协议可以抵抗外部和内部攻击。
Quantum key agreement requires all participants to recover the shared key together, so it is crucial to resist the participant attack. In this paper, we propose a verifiable multi-party quantum key agreement protocol based on the six-qubit cluster states. A verifiable distributor who preserves some subsequences of the six-qubit cluster states is introduced into this protocol, thus the participants can not obtain the shared key in advance. Besides, the correctness and simultaneity of the shared key are guaranteed by the trusted design combiner and homomorphic hash function. Furthermore, the security analysis shows that the new protocol can resist the external and internal attacks.
