Diverse application service such as mobile payment, access control or smart poster have been provided by using smart devices with built-in Near Field Communication technology. Especially, a mobile payment system can provide convenience to its users, but it also can poses including data disclosure while transmitting. There are vulnerabilities while generating session keys used to encrypt data in transaction processes as proposed in KS X 6928, the standard for mobile payment system. Therefore, in this thesis, I analyzed weaknesses of session keys used to encrypt transaction data and proposed a more secure mobile payment system based on NFC to enhance security. The proposed system will provide security functionalities such as key freshness, mutual authentication and key confirmation.

The Web or Mobile channel of previous Web access authentication system for a payment only provides the authentication of remote users, and does not provide the authentication between a user and a bank/financial institution. Therefore, this paper proposes the Transaction Certificate Mode(TCM) for a payment which can preserve the mutual authentication between a user and a bank/financial institution for Web-based payment systems. The proposed system has designed for wireless network instead of Secure Electronic Transaction (SET) designed for wired electronic transaction. In addition, this system with TCM is able to support an account-based transaction for wireless networks instead of a disadvantage of SET such as a card-based transaction for wired networks. Therefore, customers can check their balances without logging on their bank's web site again due to mutual authentication between a customer and his bank/financial institution.

In E-mail based accounting system, the remitter does not have need to find collector's account number. To transfer money to a collector's account, what remitter need is just a collector's E-mail address. But the current E-mail based accounting systems are built on SSL technology. Basically SSL provides some security services - confidentiality, user authentication and data integrity, but does not provide non-repudiation. So, in the current E-mail based accounting system, it is possible to deny transaction. And there is no receipt of transaction. In this paper, we design and implementation of a S/MIME applied Secure Payment Mechanism. In our system, every account information - account number, receiver name, amount of money, etc. - is included in a 'check' message. And this message is protected under the Secure Web-mail using S/MIME. In a view point of the convenience, users using our system do not have need to find collector's account number. And in a view point of the security, our system provides confidentiality, user authentication, data integrity and non-repudiation. Moreover our system provides a receipt.

The increase of the smartphone users has popularized the mobile payment and the mobile credit card users are rapidly getting increased. The mobile credit cards that currently used provide its users with the service through downloading mobile credit card information into USIM. The mobile credit card saved in USIM has the minimized information for the security and is based on PKI. However certificate-based payment system has a complicated procedure and costs a lot of money to manage the certificates and CRL(Certificate Revocation List). Furthermore, It can be a obstacle to develop local e-commerce in Korea because it is hard for foreigners to use them. We propose the secure and efficient mobile credit card payment protocol based on certificateless signcryption which solve the problem of certificate use.

This study is directed to compare the payment systems between conventional and internet, under international commerce. A stable and secure payment system is necessary for the progress of e-business through the internet. There are three typical methods of payment system in conventional transactions; the letter of credit(L/C) basis, the collection basis and the remittance basis. The exporter prefers L/C basis because of authentic payment, financial convenience and reduced risk Buyers and sellers who have enjoyed long creditable relationships use carefully the collection basis. The remittance basis is adequate for small amount payment for sample. In this paper, the merits and demerits of electronic payment system are compared to the conventional payment one. Internet payment system has an advantage of speed-up in payment against the conventional, but has a limited usage in the area of consumer based(B to C) transaction. The conventional payment system has been becoming overwhelm electronic payment one in the business to business(B to B) area.

SET is one of the useful protocol for credit payment in the Electronic market. Since, the delivery problem is conformed to delivery cooperation not payment problem, the classic SET protocol didn\`t consider about the certification of delivery. But the environment of electronic market be changed to manage the sold, delivery and payment etc.. In this paper, based on this consider, we propose a new SET protocol which has an function to verify the delivery based on SKP and verify it after analyzed by Petri nets. Specially, we consider SKP between Customer, Merchant, and Acquirer for improve the verify function.

Dramatic changes are beginning to occur in payment system according to increase electronic commerce. and so electronic money as a new payment system are increase role in new and innovative systems. There are two type Electronic money as a IC card type and network-type. Advanced card technologies such as IC-card are playing an increasingly important role in new and Innovation system. The merit of IC-card are more capacity, more secure, more reliable, quick and easy to update, secure offline processing, enabling technology etc than magnetic stripe card. And so many countries began using experiment of IC- card and our country began October 13 in Cheju island. Then there are four types using-experiment (K-cash, VISA-cash, A-cash, MONDEX) in Korea. There are some problems such as standards, widely using, high cost, double investment etc. I think that important things in IC-card using is an international- standardizations and issuing corporation.

Recently, interest in Fin-Tech, a compound word of finance and technology, has been increased. However, Fin-Tech that is a mixture of finance and IT is exposed in terms of security. In this paper, we propose a method to solve the security-related problem that occurs in the financial sector where the Fin-Tech is used. Proposed method found out different problems of services which are provided by companies through a variety of financial sectors and described a method to facilitate the security service. In particular, proposed method presents a service plan to secure safety and to minimize the damage. Also, proposed method set an objective to stabilize financial services based on analyzed result after analyzing the problems of existing FinTech security services.
