| Abstract(in English) | In the spread of electronic commerce such as an electronic auction, an electronic mall through Internet, the most important benefit of electronic commerce is that anyone can join anywhere in anytime. As a result, subject with whom we make a contract have rapidly spreaded. However, we have no idea how to guarantee the validity or quality of shops, goods, persons which are unfamiliar to us. In such a case, a signature of a third party that guarantees the transaction, is effective. In this paper, we propose a new concept of signature scheme with a guarantee, give the necessary features. Furthermore, we discuss why no existing scheme realize a signature scheme with a guarantee, propose a formal model and a basic scheme. |
