摘要

提出了一种基于GHZ(greenberger - horn - zeilinger)状态的多方量子确定密钥分配协议。三方可以在GHZ状态的帮助下构建密钥。在我们的协议中,密钥可以是一个确定的字符串,而在以前的协议中,密钥是在密钥分发过程中构建的随机字符串。我们证明了我们的协议是由量子力学定律保证无条件安全的。

Multiparty quantum determined key distribution protocol using GHZ states
A multiparty quantum determined key distribution protocol using GHZ(Greenberger-Horne-Zeilinger) states is presented in this paper. Three parties can build a key with the help of GHZ states. The key can be a determined string in our protocol while the key is a random string built in the process of key distribution in previous protocols. We prove that our protocol is guaranteed to be unconditionally secure by the laws of quantum mechanics.
