| 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.
