Fair Electronic Payment Scheme Based on DSA

We present a multi-signature scheme based on DSA and describes a faireleetronic payment scheme based on improved DSA signatures. The scheme, makes both sides in e-qualpositions during the course of electronic transaction A Trusted Third Party (TTP)is involved in thescheme to guarantee the fairness of the scheme for both sides. However, only during the course ofregistration and dispute resolution will TTP be needed TTP is not needed during the normal paymentstage.

The Digital Currency of China’s Central Bank:Digital Currency Electronic Payment(DCEP)

DCEP is the Chinese version of Central Bank Digital Currency(CBDC).It is the only legal digital currency in China and meets four conditions:(a)it is issued by the central bank;(b)it is digitized;(c)it is account and wallet based;(d)it is oriented towards the general public.As a retail central bank digital currency,it has three main technical features:a“tiered limit arrangement”(small-scale payments can be made anonymously while large-scale payments cannot),a“two-tier operating system”(as with the central bank-commercial bank traditional model),and a“dual offline payment system”(supporting both parties of the transaction).Compared with CBDCs in other countries,China’s DCEP has smaller economic impacts,more obscure strategic goals,and more scarce technical details.But its progress in testing is ahead of central banks of other countries.This article is based on public information and is intended to explain what DCEP is and why and how it was developed.It also offers suggestions for future research.

Towards the Advancement of Cashless Transaction: A Security Analysis of Electronic Payment Systems

In recent decades, day-to-day lifestyle requires online payments as easy and simple solutions to several financial transactions, which makes the concept of Electronic payment Systems very popular in the growth of a cashless society. In fact, cashless transactions through simple mobile apps are not merely a concept anymore rather are implemented robustly and being used extensively. On the dark side, obvious financial benefits are making these apps vulnerable to being attacked, which can be successful through security breaches. These cybersecurity issues need to be traced out and resolved to make the financial transactions through an app secure and trustworthy. In this paper, several related papers are analyzed to trace out possible cybersecurity issues in the domain of Electronic Transaction System. The objective is to establish sufficient theoretical background to propose methodologies for measuring security issues and also identify the security strength of any FinTech application and provide standard security metrics.

The security of electronic payment is one discusses the secure mechanism and transaction process of the key problems in electronic commerce. This paper of the two electronic payment protocols SSL and SET, and presents the differences between them on security, function and practicality. SSL takes an active role in current electronic payment. With high security and perfect specifications, however, SET isn＇t widely used at present because of its complexity. But it will change in the future.

A Trusted Smart Phone and Its Applications in Electronic Payment

With the growing intelligence and popularity of mobile phones, and the trend of cellular network＇s convergence to IP based network, more and more mobile applications emerge on the market. For mission critical applications, like the electronic payment which will be discussed in this paper, the lack of trust in the underlying mobile infrastructure and secure interface to legacy systems （for this case, the banking systems） poses obstacles to their widespread presence in mobile services. Recently, the exposure of hacking of iPhone and other smart phones further emphasizes the criticality of establishing a trust platform for mobile applications. This paper analyzes the building blocks of the trusted smart phone, and proposes a framework to provide a trusted platform for mobile electronic payment. Such a proposed system may allow direct interface to the banking systems due to the banking industry recognized strong security, and hence, may enable its widespread use.

An Efficient Fair Electronic Cash System

In this paper, an efficient fair e-cash system is presented. Based on the improved Brands’ e-cash scheme, it is expanded by adding two roles, government and judges. The user can keep unconditionally anonymous in normal transactions. Authorized by the judges, the government can remove the identity of an illegal user with the help of the bank. So such misuse as blackmailing or money laundering can be prevented. Therefore, this scheme is more efficient, more suitable for adopting pre-processing and post-processing and more practical. In the paper, the details of the scheme are described, its security is proved, and its efficiency is analyzed.

Impact of International Networks on Standardization Process in Banking Industry： Example of Secure Electronic Transaction （SET） Initiative

The purpose of this article is to present and interpret the case study of the secure electronic transaction （SET） scheme of Internet security, as an illustration of the necessary construction of interoperability solutions for financial services. The interpretation of case data with actor network theory （ANT） provides an illustration of power coalitions among banks to create a de facto standard for transnational electronic payment security on the Internet. After a step of protecting its political interests and well-known technological solutions, the coalition understands that its mission becomes a matter of life and death for its members： Brand-new currency has been invented on the Web and one could develop business and monetary transactions without the banks. This interpretative stage tells us much about the transnational mechanisms of regulation and standardization as well as the ＂translation＂ steps regarding these transnational organizations. However, an additional step has to be added to this interpretative step, a step of framework construction. The aim is to help managers of the transnational firms involved in regulations and standardization to anticipate the evolutions and make relevant decisions. The framework has three distinctive characteristics： the ability to help conception, the ability to help conceive problems ＂ex ante＂, and the ability to facilitate collective conception of strategic maneuvers.

The coordinated development of cross-border e-commerce and cross-border logistics research

The cross-border e-commerce further development, its development is facing more and more challenges and bottlenecks.

Combined with cross-border e-commerce with cross-border logistics development present situation and the bottleneck problem, by means of literature data collection and investigation, the cross-border e-commerce with cross-border emphatically analyzed the present situation an-d problems of the coordinated development of logistics. Series and put forward the improvement measures, to promote the coordinated development of cross-border e-commerce and cross-border logistics and subsequent research has import-ant significance.

Financial literacy,behavioral traits,and ePayment adoption and usage in Japan

This study investigates how financial literacy and behavioral traits affect the adoption of electronic payment(ePayment)services in Japan.We construct a financial literacy index using a representative sample of 25,000 individuals from the Bank of Japan’s 2019 Financial Literacy Survey.We then analyze the relationship between this index and the extensive and intensive usage of two types of payment services:electronic money(e-money)and mobile payment apps.Using an instrumental variable approach,we find that higher financial literacy is positively associated with a higher likelihood of adopting ePayment services.The empirical results suggest that individuals with higher financial literacy use payment services more frequently.We also find that risk-averse people are less likely to adopt and use ePayment services,whereas people with herd behavior tend to adopt and use ePayment services more.Our empirical results also suggest that the effects of financial literacy on the adoption and use of ePayment differ among people with different behavioral traits.
