Abstract

In this paper, on the design process of a multiparty quantum key agreement protocol within a d $d$ -dimensional Hilbert space is elaborated upon. A circular-type multiparty quantum key agreement protocol based on the generalized Bell state is introduced. To enhance security against external attacks, n $n$ decoy states into the transmission process is incorporated. Transmission sequences of the generalized Bell state and decoy states are passed between participants. The participants then encode their secret information into the corresponding particles. Ultimately, all participants are able to derive the same key. In addition, a combination of d $d$ -dimensional Pauli operators is utilized, making the proposed protocol feasible with current technology. Analysis and protection against intercept-resend attack, entangle-measure attack and dishonest participants attacks, demonstrating the feasibility of the protocol in a d $d$ -dimensional Hilbert space. The protocol has certain advantages over other protocols in terms of a comprehensive consideration of security and efficiency.

基于 d$d$ 维贝尔态的多方量子密钥协议
本文阐述了-维希尔伯特空间内多方量子密钥协议的设计过程。本文介绍了一种基于广义贝尔态的循环型多方量子密钥协议。为了增强对外部攻击的安全性,在传输过程中加入了诱饵态。广义贝尔态和诱饵态的传输序列在参与者之间传递。然后,参与者将其秘密信息编码到相应的粒子中。最终,所有参与者都能得到相同的密钥。此外,还利用了-维保利算子的组合,使得所提出的协议在当前技术条件下是可行的。针对拦截-发送攻击、纠缠-测量攻击和不诚实参与者攻击的分析和防护,证明了该协议在-维希尔伯特空间中的可行性。与其他协议相比,该协议在全面考虑安全性和效率方面具有一定优势。
