Abstract
In this paper, we propose a refined proxy deposit protocol based on the scheme proposed by Yu and Lei, A proxy deposit protocol for e-cash systems, in: ICCSA2001, 2001, p. 289 and implement two mathematic models (for ElGamal and RSA scheme) base on the scheme of Chen et al., refined proxy deposit protocol for e-cash systems, in: ICCSA2002, 2002, p. 141. And in consideration of the relationship in most typical e-cash scheme (various studies), a merchant must maintain an account at the issuer for depositing the received e-cash from customers. Since there will be a lot of issuers in the real world, each merchant must maintain an account at each issuer for depositing all kinds of e-cash. In order to reduce the onus of the merchants, the concept of deposit-delegation protocol will be introduced in this paper such that a merchant only has to maintain an account at its trading bank (as an acquirer) and delegates all deposit business to it.
