摘　　要：证券交易所的股票交易数据库中包含大量敏感信息,用户查询该数据库时保障账户及数据库的隐私十分重要.分析了非对称量子密钥分配(QKD)及其优良特性,提出了一种基于非对称QKD的不经意集合元素映射判定协议.该协议在查询数据库时保证了用户和数据库的隐私。安全性分析结果表明,该协议能有效抵抗量子存储攻击、伪造量子态攻击和纠缠测量攻击,具有很高的信道损耗容忍度。The stock transaction database contains a lot of sensitive information in stock exchange. It is very important to guarantee privacy of the account and database when the user queries the database. The asymmetric quantum key distribution（QKD） and its excellent properties are analyzed. An oblivious set- element mapping decision protocol is proposed based on asymmetric QKD. The protocol ensures the privacy of both the user and database when querying the database. Security analysis results show that the protocol can effectively resist the quantum memory attack, fake quantum state attack and entangle-and-measure attack. It has a high channel loss tolerance.
