Research For Computer Virus Mathematics Propagation Model On Internet

In recent years, the computer technology is becoming mature and Internet is becoming widespread gradually. in the same time, the computer virus technology is increasing rapidly and the harm to us becomes more and more serious. We can not neglect the damage which it brings to us. The high attention has been paid to spread of network virus on the Internet and a lot of researches have been done.These years, the research for complex network is developing vigorously. Researchers are from the domain of graph theory, network and statistic physics etc. Lots of researches indicate that complex network, regular network and stochastic network have different statistical characters. The exiting complex system in the reality can be described by the complex network. Although Internet is built up by human, nobody can know what the buster is and how it runs. Depending on its high complexity, Internet can be thought as a ecosystem which consists of computers. Professor Xuesen Qian said Internet is a typical complex large system and Internet network is a complex network.The spread and extent of computer virus on the Internet can be considered to be a certain network publishing. The Internet topologic structure effects and restricts the virus spread. This text is to analyzing the influence of network structure to virus spread in terms of Internet complexity; introducing the typical computer virus mathematics propagation model and establishing an email propagation model on the basis of previous work. This has avoided the influence of the network structure to the virus spread to a certain extent and can reflect objectively the spread characteristics of the email virus.
