Abstract: Ranking the search results and returning the most matched documents is an important and basic function for searchable encryption technique.In order to support such function in asymmetric searchable encryption,this paper proposes a method to transform the asymmetric structure to symmetric structure.Combining with the preserving-order encryption,searching in the mixed encrypted documents is realized.In comparison with prior works that only support symmetric encryption,the algorithm supports asymmetric encryption.Experimental results show that the new algorithm is efficient and practical.

摘要: 可搜索加密算法的基本功能之一是对搜索结果进行排序并返回最佳匹配文件。为使该功能在非对称可搜索加密算法中实现,将非对称加密结构转换为对称加密结构,并结合保序加密算法,提出一种在非对称可搜索加密算法上实现排序查询功能的方案,进行混合加密密 文的检索。实验结果表明,与传统的只支持对称可搜索加密结构排序方法相比,该方法支持非对称加密,具有较好的检索效率,并且应用性强。
