高效的可验证多关键字密文检索
发布时间：2018-08-18 18:33
【摘要】：现有的大部分可搜索加密方案不能实现细粒度访问控制,也不能精确地验证搜索结果的正确性,并且单关键字检索会返回大量不相关文档以至于降低用户搜索体验.为此,借助密文策略属性加密和私有审计服务器,文中提出一种高效的可验证多关键字密文检索方案.严格的安全分析表明,文中方案在随机预言模型中能抵抗住关键字选择攻击,同时在实际数据集上的实验结果也表明,该方案在实际应用场景中是可行的、高效的.
[Abstract]:Most of the existing searchable encryption schemes can not implement fine-grained access control and can not accurately verify the correctness of search results and single keyword retrieval will return a large number of unrelated documents and reduce the user search experience. In this paper, an efficient and verifiable multi-keyword ciphertext retrieval scheme is proposed by means of ciphertext policy attribute encryption and private audit server. Strict security analysis shows that the proposed scheme can resist keyword selection attacks in the stochastic prediction model, and the experimental results on the actual data sets also show that the scheme is feasible and efficient in practical application scenarios.
