摘　　要：为应对多方数据查询中潜在的信息泄露、身份暴露以及查询内容泄露等安全风险,设计了一个保护多方隐私的匿名查询方法。通过结合ElGamal同态加密技术、不经意传输协议以及一次性会话密钥等多种加密手段,提出了一种基于匿名查询的双向隐私保护方法。该方法引入代理节点来执行所有的查询操作,从而有效隐藏查询方和被查询方的原始数据及查询行为,并支持多个机构在保护各自数据隐私的同时进行联合查询。通过测试验证,该方法可以提供高效的查询性能和准确的查询结果,有效保障各参与方的数据安全。To address potential security risks such as information leakage,identity exposure,and query content leakage in multi-party data queries,this paper proposes an anonymous query method that protects the privacy of multiple parties.A bidirectional privacy protection method based on anonymous queries is proposed by combining multiple encryption methods such as ElGamal homomorphic encryption technology,unintentional transmission protocol,and one-time session key.This method introduces proxy nodes to perform all query operations,effectively hiding the original data and query behavior of the querying and queried parties,and supporting multiple institutions to perform joint queries while protecting their respective data privacy.Through testing and verification,the method can provide efficient query performance and accurate query results,effectively ensuring the data security of all parties involved.
