This paper proposes that in addition to known factors of electronic commerce B2C websites such a design of websites, security of websites and familiarity of website influence customers trust in online transactions. This paper presents an application of expert system on trust in electronic commerce. Based on experts’ judgment, a frame of work was proposed. The proposed model applies ANFIS and Mamdani inference fuzzy system to get the desired results and then results of two methods were compared. Two questionnaires were used in this study. The first questionnaire was developed for e-commerce experts, and the second one was designed for the customers of electronic websites. Based on AHP method, Expert Choice software was used to determine the priority of factors in the first questionnaire, and MATLAB and Excel were used for developing the fuzzy rules. Finally, the fuzzy logical kit was used to analyze the generated factors in the model. Our study findings show that trust in EC transactions is strongly mediated by perceived security.展开更多

To get a big market on the Web, a special security infrastructure would need to be put into place transforming the wild-and-woolly Internet into a network with end-to-end protections. XML (extensible Markup Language) is widely accepted as powerful data representation standard for electronic documents, so a security mechanism for XML documents must be provided in the first place to secure electronic commerce over Internet. In this paper the authors design and implement a secure framework that provides XML signature function, XML Element-wise Encryption function, smart card based crypto API library and Public Key Infrastructure (PKI) security functions to achieve confidentiality, integrity, message authentication, and/or signer authentication services for XML documents and existing non-XML documents that are exchanged by Internet for E-commerce application.展开更多

Security of electronic commerce includes communication security, secure payment and goods delivery. Few solutions take merchant fraud problem into account despite its important role in electronic commerce. Disputes resolution is one way to solve merchant fraud but in general it is only useful for online information goods or judgement of fraudulent side. This paper focuses on how to solve merchant fraud problem. As previous electronic commerce schemes cannot solve merchant fraud problem due to its inherent weakness in structure, we put forward a new revolutionary scheme that is named ELC(electronic letter of credit) as it simulates letter of credit commonly used in imports and exports. ELC is a revolutionary progress in electronic commerce as it solves merchant fraud problem without weakening security of other aspects. An electronic commerce system prototype, called SEMALL, is under implementation. SEMALL consists of an electronic payment system named BEARCAT and a Web Mall named VE. BEARCAT is developed on the basis of ELC as an instance of ELC scheme. The process of a BEARCAT transaction is described and analyzed detailedly in the paper. ELC scheme can greatly push development of electronic commerce.展开更多

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.展开更多

To prevent the treachery from the participants in electronic commerce, in this paper a secure electronic payment scheme is proposed and its security is analyzed. This scheme can prevent the treachery only with the aid of an un-trusted third party. It is very simple and it also improves the security and provides the non-repudiation, accountability, fairness and privacy.展开更多
