A software framework for non-repudiation service in electronic commerce based on the Internet

We propose a software framework for non-repudiation service in e-commerce (electronic commerce) on the Internet. The proposed software framework is an explicit security framework for notary service. In the framework we propose a systematic design methodology that provides a security class concept. Our framework can be differentiated from others. First, unlike other frameworks, it is interested in a successful completion of ecommerce transactions by supporting non-repudiation of service. Second, the proposed framework is based on dynamic adaptive mechanism that improves the performance of e-commerce transactions. Keywords-non-repudiation; security; electronic commerce;
