| Abstract: | Internet worm has severely threatened Internet security.To detect and defense the Internet worm becomes an important research topic in the field of network security.The estimator of worm infecting rate was proposed based on the Kalman filtering.The mathematical model was established and the corresponding filter equations were given.The advantage of the method is that the estimate value can be revised constantly.Simulation results show the estimator based on the Kalman filtering is effective and reliable in ... |
