物联网技术和云存储已经显着发展，包括私人信息在内的许多类型的数据已经逐渐外包。针对这种情况，需要新的方便的功能，例如算法和密文上的关键字搜索，以允许用户在不泄露查询结果、密文内容等的情况下获得信息。此外，可搜索对称加密（SSE）的架构是一个合适的和有效的数据外包解决方案。在本文中，我们专注于SSE计划，它采用了一个安全的索引搜索的关键字。在传统的研究中，它已被广泛认为是该计划的搜索是否被包含在加密文档中的查询关键字或没有。另一方面，我们还考虑到查询关键字在文档中的位置，目标是矩阵类型的数据格式。该方法使管理员能够搜索在CSV类格式数据中每行或每列列出的个人信息。
IoT technologies and cloud storages have been developed remarkably, and many types of data including private information have been gradually outsourced. For such a situation, new convenient functionalities such as arithmetic and a keyword search over ciphertexts are required to allow users to obtain information without leaking queried results, contents of ciphertext, and so on. Especially, searchable encryptions have been paid much attention to realize a keyword search on an encrypted domain. In addition, an architecture of searchable symmetric encryption (SSE) is a suitable and efficient solution for data outsourcing. In this paper, we focus on an SSE scheme which employs a secure index for searching a keyword. In conventional studies, it has been widely considered that the scheme searches whether a queried keyword is contained in encrypted documents or not. On the other hand, we additionally take into account the location of the queried keyword in the documents by targeting a matrix-type data format. The method enables an administrator to search personal information listed per line or column in CSV-like format data.
