隨著云計(jì)算、大數(shù)據(jù)等新興信息技術(shù)的迅速發(fā)展,大量資源密集型計(jì)算任務(wù)被外包到云服務(wù)器。云計(jì)算模式給用戶提供高質(zhì)量數(shù)據(jù)服務(wù)的同時(shí),也大大減輕了資源受限用戶對數(shù)據(jù)的計(jì)算和存儲(chǔ)開銷。然而,云環(huán)境下數(shù)據(jù)所有權(quán)與管理權(quán)分離成為常態(tài),這使得傳統(tǒng)針對明文數(shù)據(jù)的檢索方法無法直接應(yīng)用于云環(huán)境下密文數(shù)據(jù)的檢索。因此,如何實(shí)現(xiàn)云環(huán)境下密文數(shù)據(jù)的高效檢索已經(jīng)成為云計(jì)算安全領(lǐng)域的研究熱點(diǎn)之一�？伤阉骷用芗夹g(shù)通過建立以關(guān)鍵詞為核心的數(shù)據(jù)索引來實(shí)現(xiàn)密文的高效檢索,得到了學(xué)術(shù)界和產(chǎn)業(yè)界的廣泛關(guān)注�，F(xiàn)有的可搜索加密方案主要圍繞以下三方面展開研究:首先,研究高效密文檢索方法,降低通信和計(jì)算復(fù)雜度,實(shí)現(xiàn)對大規(guī)模數(shù)據(jù)集的快速檢索;其次,研究前/后向安全的密文檢索方法,支持動(dòng)態(tài)數(shù)據(jù)的安全檢索;最后,研究多模式密文檢索方法,設(shè)計(jì)符合實(shí)際檢索場景的查詢方案。連接關(guān)鍵詞檢索作為多模式檢索的典型方式之一,在效率和安全性方面仍然存在不足之處。首先,在多用戶數(shù)據(jù)檢索場景中,授權(quán)用戶執(zhí)行數(shù)據(jù)檢索時(shí)受到文檔解密權(quán)限的限制,從而導(dǎo)致服務(wù)器返回的檢索結(jié)果中可能存在用戶無法解密的數(shù)據(jù),這無疑增加了系統(tǒng)的通信和計(jì)算開銷;其次,在動(dòng)態(tài)數(shù)據(jù)檢索場景中,現(xiàn)有...
