论文摘要
在本文中，根据D级量子系统中的铃铛纠缠状态的纠缠交换建议，建议多方量子私人比较（MQPC）方案，该方案可以通过一个方案执行n个用户的秘密二进制序列的相等性比较。详细的安全性分析表明，外部攻击和参与者攻击都无效。建议的方案不需要通过量子密钥分布（QKD）方法在N用户之间建立私钥来加密秘密二进制序列。与以前基于D级CAT状态和D级钟形状态的MQPC方案相比，建议的方案在量子资源，第三方（TP）和Qubit效率方面具有明显的优势。
In this paper, a multi-party quantum private comparison (MQPC) scheme is suggested based on entanglement swapping of Bell entangled states within d-level quantum system, which can accomplish the equality comparison of secret binary sequences from n users via one execution of scheme. Detailed security analysis shows that both the outside attack and the participant attack are ineffective. The suggested scheme needn't establish a private key among n users beforehand through the quantum key distribution (QKD) method to encrypt the secret binary sequences. Compared with previous MQPC scheme based on d-level Cat states and d-level Bell entangled states, the suggested scheme has distinct advantages on quantum resource, quantum measurement of third party (TP) and qubit efficiency.
