    Abstract: With the rapid development of electronic commerce, the secure and practical electronic payment protocol is one of the most important issues today. For most typical e-cash systems, the three major roles are an issuer, a customer, and a merchant. A merchant maintains an account at the issuer so that the issuer can transfer the corresponding fund into its account for a successful deposit. However, a lot of issuers issue different e-cash in reality. A merchant needs to maintain many different accounts for each issuer to accept all kinds of e-cash.Management of accounts becomes a heavy burden. Therefore, Yu et al. proposed a proxy deposit protocol to solve this problem as described above. However, their scheme has a weakness and we will try to remedy the security weakness.
