Abstract:

Active worms spread in an automated fashion and can flood the Internet in a very short time. In this paper, we present an active worm propagation mode  l with a discrete time, referred to as Discrete Time Worm Propagation （DTWP）, which considers the situation of anti-worms. Compared with the AAWP mode el, our DTWP model can provide better understanding and prediction of the upper propagation trend of active worms.

Key words: （active worm, scanning strategy, propagation model, epidemic model）
