Abstract(in English) | In recent years, there have been increasing opportunities for a single user to have multiple devices. A similar situation will happen in identity-based cryptography, that is, a single user stores the private key in multiple devices. Therefore, in SCIS 2021, we proposed decryption-controllable identity-based encryption, where a user can add and remove devices storing the private key, and its security notion. This report considers selective and adaptive security of decryption-controllable identity-based encryption and defines three other security notions. We also discuss relations among the four security notions. |
