In this paper, we propose a new type of authentication system, disposable zero-knowledge authentication system. Informally speaking, in this authentication system, double usage of the same authentication is prevented. Based on these disposable zero-knowledge authentication systems, we propose a new untraceable electronic cash scheme satisfying both untraceability and unreusablity. This scheme overcomes the problems of the previous scheme proposed by Chaum, Fiat and Naor through its greater efficiency and provable security under reasonable cryptographic assumptions. We also propose a scheme, transferable untraceable electronic cash scheme, satisfying transferability as well as the above two criteria, whose properties have not been previously proposed in any other scheme. Moreover, we also propose a new type of electronic cash, untraceable electronic coupon ticket, in which the value of one piece of the electronic cash can be subdivided into many pieces.
