Game Coevolution Between E-commerce Network Intrusion Detection System Model

With the popularization of information technology and computer networks, the Internet has been playing a more and more important role in the various aspects of our daily life and work. E-commerce makes use of computer technology, network technology, multimedia technology to realize the digitalization, electronization and and internationaization of commercial activities. And it has evolved into "the information economy", which takes advantage of the Internet to do business. On the one hand, e-commerce makes people’s lives more convenient, and they are able to buy the goods they need without leaving their home; on the other hand, it can also helps the companies to expand the market, reduce the cost and improve their market competitiveness.Though e-commerce is quite popular among enterprises and customers for its convenience and efficiency, at the same time it also has its own concerns. The security problem of e-commerce has always been restricting the scale and speed of the development of e-commerce. Mainly relying on the internet, it faces threats from attacks and illegal intrusion on the internet. This dissertation primarily focuses on the technology of detecting illegal intrusion on the network of e-commerce. Efforts will be made in the following aspects:1. It explores ways to realize the collaboration of different Distributed Intrusion Detection Systems on the e-commerce network with a large-scale and multiple management domains.2. In the increasingly serious network environment, various e-commerce networks are confronting the similar security problems and this study tries to design a collaborative mechanism which enables various e-commerce networks work together to fight against the intrusion on the internet.3. Each electronic commercial enterprise is free to choose to join the collaborative mechanism, and all the enterprises are seen as a Game group with bounded rationality. This thesis analyzes the collaborative strategy employed by the enterprises through establishing the evolutionary game theory and then gets to know evolutionarily stable strategy (ESS) this group employs, ie, the proportion of electric commercial enterprises joining this collaborative mechanism is dynamically getting close to the evolutionary stable strategy.4. It makes a stability analysis of the evolutionarily stable strategy and offers its instructional meaning, ie, by adjusting the parameters to encourage more electronic commercial enterprises to join the collaborative mechanism detecting intrusion and eventually gain superiority in the market competition.
