Abstract

Today, e-commerce services became more popular on the Internet and the web. Network
security is extremely essential for e-commerce services, and it is always the key to the
success of e-commerce (e-commerce). In this article, we address various security problems
concerning both the conventional and the new generation e-commerce model, such as P2P
authentication, authorization, non-repudiation, and integrity. By examining the key
characteristics of P2P e-commerce, we summaries several trust model design concepts in ecommerce.
We provide a comprehensive overview of network security problems relating to
e-commerce and e-commerce applications, and offer a related e-commerce security
research framework. In contrast with other security approaches, we think that as long as
security concerns are properly handled, P2P e-commerce will achieve tremendous success
on future e-commerce marketplaces.
