The smart card with the cryptography and VLSI technologies makes it possible to implement the electronic cash easily. A number of electronic each schemes have been proposed by many cryptographic researchers. In this paper, we propose a practical electronic cash system, using blind digital signature scheme. Schnorr's authentication scheme based on the discrete logarithm problem, and the hierarchical cash tree based on two one-way hash functions for dividable payment. Thisf electronic cash scheme has such properties as privacy of the payment, off-line payment, non-reuseability of cash, transferability of cash to another customer, and dividable payment of cash. This electronic cash protocol is well suited for implementing in smart card.

The Purpose of this Article is to analyze the special settlement and electronic settlement system in the international trade. First, Factoring is a fast, easy and flexible way to improve a company's cash flow and generate working capital for the company. Factoring can be short-term or part of an ongoing financing program. New companies can benefit as well, since there is no requirement for a long-term credit history. Second, Forfaiting is a method of trade financing that allows exporters to obtain cash and be free of all risks by selling their medium term receivables on a 'without recourse' basis. Forfaiting can be an alternative to export credit or insurance cover, especially for those transactions in which the export credit agency is not open to a particular country and/or bank. Third, The Bolero System is jointly financed by SWIFT(Society for World International Financial Telecommunications) which handles most of the electronic funds transfer for banks, and the Through Transport Mutual Assurance Association(the TT Club), a mutual insurance association most of whose members are drawn from the Multimodal transport industry or transport intermediaries. Fourth, TradeCard is a payment and settlement system that is an alternative to letters of crdeit. That is, TradeCard is a business-to-business e-commerce infrastructure that enables buyers and sellers to conduct and settle international trade transactions securely over the Internet.

There have been various attempt to offer commercial service of electronic payment. Actually, however, there has been few electronic payment model that are being used commercial service. Among them, it is estimated that only TSU(Trade Service Utility) of SWIFT will be succeed in providing commercial service possibility. In Korea e-L/C Distribution & Management System was constructed and become the first e-L/C service on a global basis via e-Trade Facilitation 3 Years Project and then started offering the world first e-L/C service. Some scholars have insisted the opinion that SWIFT L/C means e-L/C, but such opinion may be wrong because SWIFT L/C means the L/C advised by SWIFT(Society for Worldwid Interbank Financial Telecommunication) under the condition that a series of procedure from the issuance of L/C to the advice is done by SWIFT system. Because perfect e-L/C should be organically connected by SWIFT network and also, the e-L/C business between overseas banks and their customers should be organically linked with each other. The purpose of this paper is contribute to the commercialization of e-L/C distribution system by studying the current status of infrastructure concerned with domestic and overseas electronic payment and future e-payment infrastructure, seeking to be introduced internationally by doing things.
