L/C allows the exporter to have a bank's payment undertaking against shipping documents required by L/C. This means that the exporter can take export proceeds from a L/C issuing bank regardless of importer's payments and therefore the L/C better mitigate importer's credit risk compared to remittance and collections. Recently the use of L/C has been on down trend in line with increasing use of T/T, causing a big change of payment system. This tells that the payment method change in Korea is positive as the change also happens same in developed countries. This however gives more buyer's credit risk to exporters and therefore a systematic solution to this negative effect is required. In Korea, export credit insurance has been widely used to cover the buyer's credit risk. But the export credit insurance is limited because of lack of government's financial support and strict evaluation of buyer and exporter. Now Korea is ranked 10the largest trading country and therefore the exporters shall find another source for credit risk protection elsewhere. And as such this paper suggest International Factoring as a tool for the credit risk protection. The International Factoring gives advantages to the exporter in terms of credit protection and advances by purchasing account receivables on a without recourse basis.

인터넷의 발달로 인하여 다양한 온라인 카드 지불 방식이 생겨나게 되었다. 그 중, 기존의 국민카드와, BC카드의 카드 결제 방식인 ISP(Internet Secure Payment) 시스템에서 ISP를 생성하는 과정이 현재의 인증 방법으로는 잠재적인 취약점이 있음을 발견하고, 이에 본인 인증을 강화하는 프로토콜을 제안한다.

전자상거래의 급격한 성장에 따라 인터넷이라는 광용 네트워크에서 보다 안전한 지불수단을 필요로 하게 되었다. 현재 SSL을 이용한 정보보호 방법과 SET를 이용한 지불 프로토콜이 표준화 및 상용화되어 있다. 그러나 SSL은 신용카드나 직불카드 번호와 같은 중요한 정보들이 사용자의 의지와 상관없이 여러 통로로 노출될 수 있으며 거래 당사자들의 인증수단이 취약하다는 단점이 있다. SET 역시 프로세스들이 복잡하고 비용 등에 부담을 주고 있다. 새로운 대안으로 SSL 기반에 특정한 상황에 SET으로 대체하는 것과 SSL에 인증기능을 강화하는 등의 새로운 연구들이 이루어지고 있다. 본 연구에서는 SET 프로토콜 기반의 새로운 지불 시스템을 제안한다.

This Paper represents time-dependent stochastic variations of common discounted cash flow formulae with explicit consideration given to inflation. The cash flow, the ratio of discounting or compounding, and the rate of inflation are allowed to vary with time in a random fashion in equations for the compound amount of a single payment, present worth of a single payment, amount of an annuity, periodic deposits to accumulate a future amounts, present worth of an annuity and capital recovery And all formulae are derived for the case of discrete random variations.

공개키 연산을 이용하는 고액 지불 시스템(Macro Payment System)은 높은 수수료로 인해 경제성이 맞지 않아 소액 지불(Micro Payment)에는 적합하지 않다. 해쉬 연산을 이용한 PayWord 프로토콜은 저렴한 메커니즘 비용과 신속한 트랜잭션 처리, 거래과정에서 브로커의 오프라인 참여로 소액 대금 결재에 적합하다. 그러나 특정 상점에만 사용 가능한 화폐가치를 포함하여, 사용자가 거래하는 상점이 많아지면 관리 저장해야 하는 해쉬 체인의 수가 늘어나는 단점이 있다. 본 논문에서는 전자화폐에 해당하는 해쉬 체인을 하나만 생성하여 여러 상점들에 안전한 지불을 수행하는 개선된 소액 지불 프로토콜을 제안한다. 제안한 방법은 지불과정에 MAC(Message Authentication Code)을 이용한 해쉬 간을 추가하여, 상점들의 공모 및 악의적인 수정을 방지한다. 따라서 사용자는 하나의 해쉬 체인만을 생성함으로써 기존의 PayWord보다 계산부담이 줄고, 여러 상점들과의 일시적인 거래관계에서도 효율적인 지불을 수행한다.

In recent years electronic fund transfers covered by the Electronic Fund Transfer Act 1978 for consumer protection and the Article 4A of Uniform Commercial Code(U.C.C.) 1989 for wholesale electronic payments in United States. Electronic fund transfers carried out by use of a wire transfer network, automated clearing house, or other communication system of a clearing house or other association of banks such as direct deposit, Fedwire, automated teller machine, point-of-sale, and credit card transactions have been increasingly common in consumer transactions and wholesale transactions. Especially, the Article 4A of U.C.C. governs the rights and obligations associated with transactions such as an issue and acceptance of payment order, execution of sender's payment order by receiving bank, and payment. These legal frameworks in connection with electronic fund transfers in United States can play a leading role in establishing model not only within the United States, but also as a basis for developments of electronic commerce law in Korea including other countries.
