| Outline of Final Research Achievements |
The importance of research and development of cryptographic techniques with variety of properties has been increasing. In this paper, we have studied cryptographic techniques with conditions, which can be processed only if its associated condition is fulfilled. In particular, we have focused on a new scheme called signdecryption, in which a decryptor needs to create a signature in order to execute decryption. We have introduced such a notion, made its definition and showed its concrete and generalized constructions. Moreover, we have studied methods to improve the condition of searchable encryption schemes.
