| Outline of Final Research Achievements |
Searchable encryption is a technique that records various data in encrypted form and identifies data containing specific keywords without decrypting them. In searchable encryption, the correspondence between keywords and the data containing them is constructed as an encrypted index. The purpose of this study is to clarify the issues involved in implementing a encrypted index.
After creating a data set for testing, we evaluated these various schemes in terms of speed, fault-tolerance, and so on. As a result, it was found that most of the problems in implementing searchable encryption can be turned into problems of elemental technology, and that no major problems arise in constructing the actual system.
