Outline of Final Research Achievements |
Nowadays cryptographic techniques are widely used to protect communication data, while digital data stored at various computers/servers are also protected by cryptography. Employing encryption techniques simply can sometimes lead to inconvenience, i.e., encrypted data need to be decrypted in the environment which may be compromised by an adversary. It is not easy to prevent server breaches perfectly, so to tackle such a situation, we work on how to process encrypted data while keeping them in the encrypted form.

Academic Significance and Societal Importance of the Research Achievements |
様々なデータを電子化し,大量に保存することが可能になった現代において,多種多様な場面で情報を活用することが求められている。集められた情報を分析することで新たな知見が得られることが期待できる一方で,機密情報は公開/共有することが難しく有効活用できていないという状況があった。そのような価値の高い機密情報を保護したまま処理することを可能とする技術の開発は,有用な情報の利活用を促すことにつながる。
