摘要
摘要:随着云计算的发展，以密文检索为核心的安全和搜索性能问题成为研究的重点。在传统的加密方案中，大多只解决了抵御外部关键字猜测攻击问题，往往忽视了诚实且好奇的云服务器问题。为了提高密文安全性，该文提出快速搜索的抵御内部关键字攻击方案。首先，引入高效的加密倒排索引结构的公钥密文搜索方案，实现关键字的并行搜索任务。其次，在构建密文倒排索引时加入数据拥有者的私钥抵御恶意云服务器的关键字攻击。与传统的公钥可搜索加密相比，该方案在很大程度上增强了搜索系统的安全性和搜索效率。

Abstract:With the development of cloud computing, the security and search performance of ciphertext retrieval has become the focus of research. In the traditional encryption schemes, most of them only solve the problem of defending against external keyword guessing attacks but ignore the honest and curious cloud server. In order to improve the security of ciphertext, an inside keyword attack scheme based on inverted index is proposed. Firstly, the private key of the data owner is added to resist the keyword attack of the malicious cloud server when the ciphertext inversion index is built. Secondly, an efficient public key ciphertext search scheme of parallel encryption index structure is introduced to realize the parallel search task of keywords. Compared with the traditional public key searchable encryption, the proposed scheme enhances greatly the security and search efficiency of the search system.
