| Abstract(in English) | Discussing security of the ID-based encryption, a kind of the public key encryption, one criterion of security is the anonymity. The anonymity is defined using a game between an adversary and a challenger. In this game, first, the adversary hands two IDs to a challenger, next, the challenger who received it encrypts using randomly selected one of the IDs, then, the adversary reveals which ID has used. We devise several definitions of the anonymity and clarify them, the relationship between proposal and conventional anonymity definition. |
