With the rapid development of Internet, computer viruses has become more and more serious, which attract more and more people's attention. Therefore, the spread of computer viruses were probed in this study. The computer virus propagation model was established, and the spread of computer viruses in different time system status and development trend were simulated. In addition, computer viruses spread...
In less than two decades, computer viruses and worms have grown from an anomaly to an everyday occurrence. In response to such a threat, the academic community has started a set of research projects seeking to understand worm behavior through creation of models. Staniford created a model to explain the propagation behaviors of worms in computer network environments. Liljenstam added a spatial perspective...
Based on both construction methods of the epidemic models and mechanism of the worm propagation, a new SIRS model for virus propagation is derived. By using the theory of differential equations, the propagation regularity of worm virus is discussed and the threshold of removing virus is gained. The analysis techniques of the mathematical model provide theoretical foundation of control and forecast...
Considering the characteristics of the propagation of worm, we can analyze it by epidemic model. In this paper, considering that to re-assembly system and the use of anti-virus software will take a period of time, so we introduce a time-delay to describe this period of time. On this basis, we build a SIDRQ model for Internet worm virus propagation depended on the two-factor model. By using the theory...
Recent years, government agencies have achieved some degree of success on strengthening the protection of software copyright and enhancing its managements and laws. According to technology acceptance model theory, the reason why consumers have intention to accept genuine antivirus software were explored from five aspects, perceived usefulness, perceived ease of use, subjective norm, self efficacy...
