Outline of Final Research Achievements

In this research, we proposed the extensions of searchable encryption schemes that could specify the searching user and could configure several conditions. Although our extension schemes assumed the existence of multi servers, they had useful properties and were secure and efficient. Furthermore, we researched the improvement of efficiency relevant to the extension schemes. From the above results, we could contribute to the security and usefulness for using encrypted data.
