Modeling and Simulation of Electronic Commerce System based on the SET protocol

The Security of on-line payment becomes the important factor to prevent the development of electronic commerce.Security electronic transaction protocol is constituted for safe on-line payment.Many kinds of information systems have been built on the protocol.This paper builds the framework of electronic business system by the protocol and set up model by Petri nets theory and tools.The problem that there is not a unitive method when a electronic commerce system is designed has been solved.At last this paper use colorful Petri theory to analyze the structure and performance of the model and verified the possibility to use the protocol.
