【摘要】：現(xiàn)有的大部分可搜索加密方案不能實(shí)現(xiàn)細(xì)粒度訪問控制,也不能精確地驗(yàn)證搜索結(jié)果的正確性,并且單關(guān)鍵字檢索會(huì)返回大量不相關(guān)文檔以至于降低用戶搜索體驗(yàn).為此,借助密文策略屬性加密和私有審計(jì)服務(wù)器,文中提出一種高效的可驗(yàn)證多關(guān)鍵字密文檢索方案.嚴(yán)格的安全分析表明,文中方案在隨機(jī)預(yù)言模型中能抵抗住關(guān)鍵字選擇攻擊,同時(shí)在實(shí)際數(shù)據(jù)集上的實(shí)驗(yàn)結(jié)果也表明,該方案在實(shí)際應(yīng)用場(chǎng)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.
